「HAPPY HALLOWEEN」は、月明かりの夜を描いたゴシック調イラストのハロウィンポスターです。コウモリの翼のようなクリーム色の大文字が満月とコウモリの下に並び、灯りのともるお化け屋敷、霧の墓地、枯れ木、光るジャック・オ・ランタン、緑のゾンビの手がインディゴとオレンジで描かれています。見出し、「TRICK OR TREAT」の行、下部の日付を差し替えて、自分のパーティーやトリック・オア・トリート用ポスターが作れます。

Create a finished, vertical front-door Halloween poster in clean, flat illustrated shapes with fine paper grain and soft mist drifting between gravestones. Use a deep indigo-purple night sky with a large full moon high overhead, pale moonlit edges on the silhouettes, and a calm open area of sky for the lettering. Render the exact headline “HAPPY HALLOWEEN” in one prominent line across the open sky, large and instantly readable. Use a bold, heavy, upright display sans with wide strokes and open counters. Each flat stroke ending flares into a small bat-wing shape with two or three pointed tips and shallow scallops; keep the body of every letter solid and legible. Set the letters in moon white, softly lit from above. Add the smaller supporting line “TRICK OR TREAT” beneath the headline, then the fine-print footer “OCTOBER 31 • AFTER DARK” near the bottom edge. Keep those lines crisp and subordinate. Stage the scene below the words: a crooked haunted house with glowing windows, graveyard fence, gravestones, and bare twisted trees in dark silhouette; a neat row of glowing jack-o-lanterns runs along the ground. A few small bats cross in front of the moon. Cool moonlight is the base light; warm pumpkin-orange glow comes only from the jack-o-lanterns and house windows. Use one restrained accent of slime green among the graveyard details. Keep the illustration balanced and inviting, with clear separation between text and scenery, generous poster margins, and no extra lettering, logos, borders, or photorealistic elements.
