Flat vector travel poster illustration of [CITY_UPPER], [COUNTRY_UPPER] ([LOCATION_DESCRIPTOR, e.g. Lake Como / the Amalfi Coast / Old Town]). Premium editorial style, mid-century modern, Scandinavian-inspired minimalism, in the spirit of a vintage [COUNTRY_ADJECTIVE] [RAILWAY/TRAVEL] poster. Simple geometric shapes, solid flat color fills, zero outlines, zero textures, zero foliage detail. Clean Adobe Illustrator vector look with a strictly limited palette, bold graphic shapes and generous breathing space.
GRADIENT RULE: solid flat fills everywhere, except two very subtle soft tonal gradients allowed ONLY on the sky and the [WATER_OR_GROUND_FEATURE, e.g. water / sea / desert sand]. Buildings, hills, [HERO_VEHICLE_PLURAL], [STREET_FURNITURE], flowers, shadows, border and text are strictly flat solid colors.
FORMAT: vertical 4:5 poster, thin cream border (#F3EADF) around the artwork, text on the cream band below the artwork.
SCENE AND VIEWPOINT: [VIEWPOINT, e.g. low viewpoint from the water] of [MAIN_SETTING], looking toward [CITY_FRONT, e.g. the lakefront / harbor / main boulevard]. [BACKGROUND_FEATURE, e.g. the steep wooded hill of X / a volcano / a mountain range] rises on the [LEFT/RIGHT], the [OLD_TOWN / DISTRICT] and [MAIN_SQUARE] sit [center-right/center-left], [FOREGROUND_AREA, e.g. open water / a plaza] fills the foreground. Three clear depth planes: foreground [FOREGROUND_ELEMENT] and [HERO_VEHICLE], midground [TOWN_TYPE], background [BACKGROUND_FEATURE_SHORT] and sky. Poster hierarchy: (1) [HERO_LANDMARK] as the main focal point on the upper-third line, (2) one strong diagonal [LEADING_LINE_ELEMENT, e.g. funicular / tram line / road / bridge] leading the eye [DIRECTION] toward the town, (3) the hero [HERO_VEHICLE] in the foreground. No other competing subjects.
SKY (top 35%): very subtle vertical gradient, deeper azure (#6DB1E6) at the top fading to paler blue (#A8D3F0) near the horizon, no banding, no glow. Two simple white cloud shapes (rounded blobs with flat bottoms), three tiny white bird silhouettes. [SKY_NOD, e.g. one small cream-and-red seaplane / hot air balloon / vintage biplane] flying in the upper center with a slim white trail line, clear of every other element.
[BACKGROUND_FEATURE_NAME] ([LEFT/RIGHT]): one large, smooth [HILL/MOUNTAIN/CLIFF] built from three flat [COLOR_FAMILY, e.g. olive-green] tones ([HEX1], [HEX2], [HEX3]), simple smooth edges, no leaf clusters, no wavy contour lines. Halfway up the slope, the small village of [VILLAGE_NAME]: 4 to 5 cream villas with [ROOF_TYPE, e.g. terracotta] roofs and one slim [LANDMARK_TOWER, e.g. church bell tower]. [LEADING_LINE_DETAIL, e.g. A thin straight cream-white funicular track runs diagonally from the base up to the village, with one small red cabin (#C9594B) on it; the track ends at the village, NOT at the summit]. Higher up stands [SECONDARY_LANDMARK_DESCRIPTION, e.g. a slim, tall, octagonal pale-concrete lighthouse tower], clearly separated from [LEADING_LINE_ELEMENT] and from every other element.
[OLD_TOWN_NAME] (center-right, fully inside the frame): [NUMBER, e.g. 7] simple blocky [ARCHITECTURE_ERA/STYLE, e.g. 19th-century] [WATERFRONT/STREET] buildings of [FLOORS, e.g. 4 to 5] floors with [ROOF_STYLE, e.g. low-pitched flat terracotta] roofs, [LAYOUT, e.g. curving gently along the shore]. Color ratio across the whole poster: about 45% cream white, 40% blue (sky, [WATER], cobalt accents), 10% coral and terracotta, 5% ochre. Buildings mostly cream white (#FBF5EA) with only three accents: soft ochre (#E3B25E), terracotta (#C9694B) and one coral-peach (#F0A58A). Every cream building has one flat pale grey-lavender shade plane (#D9D6DC) on its side wall and no other shading. Maximum 3 windows per building, drawn as simple vertical cobalt-blue strips (#2F6DB5).
In front of the buildings, the open [MAIN_SQUARE] [WATERFRONT/PLAZA]: [FRONT_ELEMENT, e.g. a plain cream-stone quay with a low parapet, and one small ferry landing pontoon with a simple flat-roofed shelter].
[HERO_LANDMARK_PLACEMENT, e.g. Set back behind the lakefront rooftops (a few blocks from the shore, NOT on the water's edge)]: [HERO_LANDMARK_FULL_NAME] seen from [VIEW_SIDE]. [HERO_LANDMARK_VISIBLE_PARTS, e.g. Only the pale marble upper body is visible: a pitched roof of the apse and transept, and a tall baroque dome on a drum with 3 slim arched windows, topped by a small lantern]. [HERO_LANDMARK_COLORS, e.g. Dome in muted verdigris grey-green (#86B5A5), body in cream-white marble]. The landmark rises well above the surrounding roofs, about 20% larger than any neighboring roof mass. [LANDMARK_EXCLUSIONS, e.g. No facade, no rose window, no statues].
Exactly 3 slim [TREE_TYPE, e.g. dark-green cypress] shapes ([HEX, e.g. #2F6B55]) between buildings, nothing more.
[WATER_OR_GROUND_FEATURE] (large, foreground and center): very subtle tonal gradient, deeper blue (#2A6FBF) in the foreground fading to lighter blue (#3F8AD4) toward the [FAR_SHORE/HORIZON]. Lighter flat horizontal reflection bars (#5FA3DD) under the [HERO_LANDMARK_SHORT], buildings and [FRONT_ELEMENT_SHORT]. No ripples, no realistic reflections. The [WATER_OR_GROUND_FEATURE] is empty apart from the hero [HERO_VEHICLE].
HERO [HERO_VEHICLE_UPPER] (lower center-right): [HERO_VEHICLE_DESCRIPTION, e.g. a classic Italian mahogany runabout in varnished brown (#A8663A) with a cream stripe, a low cabin with cobalt-blue windows] and a tiny [COUNTRY_ADJECTIVE] flag ([FLAG_DESCRIPTION]) at the stern, heading [DIRECTION] toward the [DESTINATION, e.g. quay], leaving a short flat white wake. Slightly larger than any other element.
FOREGROUND [FOREGROUND_ELEMENT_UPPER] (bottom-left): [FOREGROUND_DESCRIPTION, e.g. a cream-stone quay corner with a curved edge, two cobalt-blue mooring bollards, and one slender dark-green cast-iron lamppost with a round white lantern, with a flat pale-blue shadow shape].
FRAMING ELEMENT: a small [FLOWER_OR_PLANT_NAME, e.g. coral oleander] branch hanging in from the top-right corner only, no more than 6 [FLOWERS] drawn as flat petal clusters in two [COLOR] tones ([HEX1], [HEX2]), no flower centers, no veins, a few flat dark-green leaves. A few flat petals float on the [WATER_OR_GROUND_FEATURE] at the lower left. The branch does not touch the [SKY_NOD_SHORT], [HERO_LANDMARK_SHORT], or [SECONDARY_LANDMARK_SHORT].
ACCENT UNITY: all windows, doors, bollards and boat windows use one single cobalt blue (#2F6DB5).
TYPOGRAPHY: centered on the bottom cream band, exact spelling: "[CITY_UPPER]" in large, wide-letter-spaced, modern geometric sans-serif (Montserrat/Futura style), navy #1F3F73. Below it a short thin coral accent line (#E8605A), then "[COUNTRY_UPPER]" in small spaced capitals in dark navy. No other text.
MOOD: calm, clean, premium, slightly dreamy travel magazine feel, bright fresh daylight.
QUALITY: ultra clean edges, perfect alignment, no distortion, high resolution, print-ready.
AVOID: photorealistic, painterly, 3D render, detailed foliage, leaf clusters, brush strokes, outlines, gradients on buildings, hills or objects, glow, blur, heavy shadows, clutter, many windows, crowded village, realistic water ripples, extra boats, [WRONG_LANDMARK_TYPES_FOR_THIS_CITY], [WRONG_ARCHITECTURE_STYLES, e.g. Greek or Cycladic architecture], windmills, bistro table, chairs, watermark, distorted or extra letters.
