Create a finished 3:4 vertical Earth Day community poster, vintage 1970s heritage-print production. A warm cream cotton-paper sheet with deckled-paper grain, faint tan foxing, tiny ink specks and a deep forest-green letterpress border. At the top 18% of the page, set the exact headline “SAVE MOTHER” in two centered straight lines. Design custom retro display lettering: tall, wide, straight-sided 1970s condensed block sans forms, high x-height, low contrast, squared terminals with softly worn corners, open counters, tight but readable tracking; deep forest-green ink pressed into paper, uneven faded coverage and a shallow debossed letterpress edge. Do not use rounded psychedelic bubble letters. Directly below, a smaller centered brick-red line reads “EARTH”. The lower 52% contains the hero subject: a large hand-drawn half Earth rising from the bottom edge, its upper hemisphere visible. Use thick imperfect forest-green contour lines, simple continents, curved latitude and longitude lines, small brick-red flowers and leaves growing from the rim, and irregular sun rays in antique-gold ink behind the globe. Make it a flat screen-printed doodle illustration, not photorealistic; retain visible paper between ink strokes. Under the globe, centered in small straight all-caps letterpress type: “ONE PLANET. NO SPARE.” At the bottom, a thin forest-green rule then “22 APRIL 2027 • CITY PARK • 10 AM–4 PM”, followed by “BRING A FRIEND. LEAVE NO TRACE.” Use restrained faded red accents only for dots and flowers. Warm amber grazing light reveals the pressed paper fibers and ink relief. Clean centered poster hierarchy, generous cream margins, no modern gradients, no neon, no mockup, no extra text, no logos.
