Ein Grußplakat im Vintage-Stil mit "Happy Halloween", gedruckt auf gealtertem cremefarbenem Karton. Eine schwarze Katze mit Buckel steht auf einem grinsenden orangefarbenen Kürbis, umgeben von Fledermäusen und Ahornblättern; die dicken schwarzen Serifen-Versalien stehen auf einem welligen orangefarbenen Band oben. Ersetze die Überschrift durch deinen eigenen Gruß, Partynamen, das Datum oder die Adresse, um deine Version zu gestalten.

Create a finished portrait 3:4 matted vintage Halloween art print for framing, in the graphic language of a 1950s three-colour printed greeting card. Show the artwork inset within a broad, clean cream mat border on all four sides; the mat is part of the image, with no outer frame. Inside the mat, make a compact, balanced printed illustration on aged cream stock. At the top of the inset artwork, place a small scalloped ribbon banner carrying the exact words “Happy Halloween”. Make the lettering wide, sturdy, bold mid-century slab-serif capitals, with thick square serifs, nearly uniform stroke weight, and a lightly pressed letterpress texture at the edges. Keep the words highly legible and correctly spelled. Below the banner, make the hero subject a friendly black cat perched on a large pumpkin. The cat has an arched silhouette, pointed ears, bright cream eyes, a small cream muzzle, and a curled tail; its expression is playful and welcoming. Give the pumpkin broad, rounded orange lobes with black ink outlines and a simple curling vine. Use only three printed colours throughout: deep black, pumpkin orange, and warm aged cream. Draw as flat, neatly outlined shapes with restrained coarse halftone dots for shading, slight vintage colour-plate misregistration, softly worn print edges, faint creases, and gently yellowed paper. Add a few small black bats and orange autumn leaves around the illustration as balanced decoration, not competing with the headline or cat. Flat printed light, no gradients, no neon, no extra colours, no additional words. Preserve generous cream mat space and the feel of a charming old Halloween postcard found in an attic.
