Create a finished vertical 3:4 1950s Halloween greeting-card wall art print, designed to look like a charming vintage paper decoration found in an attic. Use warm aged cream card with softly worn corners, faint creases, coarse halftone dots, and slight orange-and-black color-plate misregistration. Flat printed light only; build shading from flat color shapes and halftone, never neon or glossy realism. Use a restrained palette of pumpkin orange, black, cream, and a small olive-green accent. Set the exact headline “Trick or Treat” large and unmistakable across the middle on a scalloped cream ribbon banner with a fine black outline. Letter it in sturdy, wide mid-century American retro slab-serif display type: heavy, nearly uniform strokes, bold square slab serifs, title case, subtly imperfect letterpress ink edges. Print the letters in rich pumpkin orange with a crisp black keyline and restrained offset black shadow for legibility. Above the banner, set the small centered greeting “A HAPPY HALLOWEEN” in compact black capitals. Below the illustration, set “OCTOBER 31” in small black capitals. Build a lively, flat-printed scene around the banner: a large friendly jack-o-lantern with a broad grinning carved face anchors the lower center, and an arched black cat with an expressive curved back and raised tail stands just behind and to one side of it. Add a few small bats, autumn leaves, and simple starbursts as supporting decoration, with olive green limited to a couple of leaves. Keep the pumpkin and cat boldly outlined, charming rather than frightening, and clearly recognizable at a glance. Arrange the motifs around the lettering without obscuring any words. Frame the composition with a simple vintage scalloped border, leaving generous cream margins like a collectible mid-century Halloween postcard. No extra words, no photorealism, no modern effects.
