"Trick or Treat" ist ein Halloween-Grußplakat im Vintage-Stil mit dem Look einer retro gedruckten Postkarte. Dicke schwarze Slab-Serif-Buchstaben mit orangem Schatten stehen auf altem cremefarbenem Karton, zwischen einer Nachtszene mit Hexe auf dem Besen und einem Kürbis mit einer buckelnden schwarzen Katze. Ersetze Überschrift, Grußzeile und Datum durch eigene Worte, um eine individuelle Halloween-Einladung oder -Karte zu gestalten.

Create a finished 3:4 portrait vintage Halloween wall-art print, like a charming 1950s paper postcard rescued from an attic. Use a strict three-colour print palette only: aged cream, pumpkin orange, and black. Leave a generous, clean cream margin around the entire design, with softly worn paper edges, faint creases, subtle age-yellowing, coarse halftone dots, and slight orange/black plate misregistration inside the printed area. Keep the print flat and graphic, with shading only from simple colour shapes and halftone. Build a strong centered, framed composition: a scalloped arch and simple ribbon banner organize the image. At the top, set the small uppercase line “HALLOWEEN GREETINGS”. Make “Trick or Treat” the dominant headline across the middle, arranged on two balanced lines, exactly as written. Use wide, sturdy, bold mid-century American slab-serif display lettering: uniform heavy strokes, square slab serifs, broad proportions, tight confident spacing. Print the letters in black with a slight pressed-ink impression and subtly softened ink edges; keep every letter crisp and highly legible. Below and partly framing the headline, show a large friendly jack-o’-lantern with triangular eyes, a broad cheerful grin, and a curled stem, in flat pumpkin orange with bold black features. Beside it, place a clearly recognizable black cat with arched back, pointed ears, curved tail, and small cream eyes, posed as a playful silhouette. Keep both figures simple, flat, warmly whimsical, and outlined in black; do not add other colours. Finish with the small line “OCTOBER 31” centered at the bottom inside the arch. Balanced, collectible, nostalgic wall art; clear separation between type and illustration, no modern effects, no gradients, no extra text, no mockup or frame outside the printed artwork.
