Create a finished, family-friendly Halloween event poster for print and social sharing, portrait 2:3. Keep all text and key artwork inside a generous print-safe margin. Use a clean, high-contrast reading order: event title largest, date and time second, then place and grouped entry details. Render every quoted line exactly, with correct spelling and punctuation; do not add any other text: “PUMPKIN CARVING CONTEST” “Carve-Off Showdown” “Saturday, October 24 · 2 PM” “Oak Street Library Lawn” “Bring your own pumpkin · Free to enter” “Prizes in three age groups” Set the headline in large, custom, hand-lettered rounded slab lettering: broad heavy strokes, open counters, slightly irregular carved notches at a few terminals, tight but distinct spacing. Keep every letter crisp and readable at thumbnail size; no drips or cracked strokes. Use warm ivory faces, pumpkin-orange inset shading and a restrained deep-plum keyline. Set supporting text in a sturdy, highly legible condensed sans, ivory on dark plum panels. Composition: small contest label centered near the top; oversized two-line “Carve-Off Showdown” below; a clearly separated, prominent date-and-time line directly beneath it. In the center-lower area, feature one large friendly carved pumpkin as the hero prop, with a glowing triangular nose and broad smiling eyes and mouth; show a few clean carving-tool silhouettes and small pumpkin shavings nearby. Place a small, simple library silhouette behind it, with a few autumn leaves. Keep the place and entry details together in a tidy, high-contrast block near the bottom, with “Prizes in three age groups” as a small final line. Keep decoration clear of all lettering. Build a playful-spooky, all-ages scene: deep aubergine night-sky background, softly lit lawn, a handful of floating autumn leaves, and a subtle crescent moon. Use pumpkin orange, warm cream and muted violet; no blood, gore, frightening faces, or horror effects. Render as polished dimensional screen-printed poster art with lightly visible paper grain, clean edges, warm internal pumpkin glow, soft rim light, and strong contrast.
