"Create a advertisement poster with a retro black and beige color scheme. The poster features a cool pigeon wearing a football jersey in purple and black, with an emblem of an bear on the crest and the word 'FISB' on it. The pigeon is perched on top of a large spoon filled with tortellini, creating a whimsical scene. In the background, there’s a woman, dressed in vintage 50s fashion, happily eating an ice cream cone. The scene should have clean lines, elegant typography, and a nostalgic feel, with a playful twist. The overall design should combine the classic vintage style with fun and unique elements, keeping the mood light-hearted and imaginative."
