A colorful vintage-style Halloween postage stamp collection design featuring six decorative stamps arranged in a 2x3 grid. Each stamp showcases different Halloween characters: a witch's cauldron with bubbling potion, a mummy wrapped in bandages, a black raven perched on a branch, a haunted Victorian mansion silhouette, a skeleton hand holding a candle, and a werewolf howling at the moon. Each stamp has decorative scalloped edges in different pastel colors - orange, blue, purple, green, and pink backgrounds. The stamps feature bold cartoon-style illustrations with clean line work and flat color fills, maintaining the same cheerful Halloween aesthetic. Postal cancellation marks appear in one corner. The design is print-ready, fully isolated on a white background with no shadows or textures, fully contained within canvas boundaries with no cut-off elements and proper margins around all elements, and intended for use in t-shirt printing. | PODspy AI Design
