Retro Black Cats Halloween Feiertagspostkarte

A bold, playful Halloween illustration bursting with mid-century modern charm. Four stylized black cats strike mischievous poses around a dramatic “Happy Halloween” banner, their bright eyes glowing in yellow, orange, and purple. The composition is energized by atomic-age starbursts, crescent moons, dots, and swooping shapes in a lively palette of teal, chartreuse, orange, violet, and black. With its clean style, whimsical motion, and retro-futuristic flair, this design feels fun, festive, and delightfully kitschy.
