Here's a display poster for Sonic Jam.
It's got the main graphic for the game large in the center with Sonic Tails & Knuckles posed dynamically in the ring. The banner logo is below it, and everything is on a 'backdrop' of many TV monitor shapes. (old style with the rounded edges) most are just colors or static, but some have little logos the words "This Is Cool" or game screen shots (bottom row) in them. There are two vertically written phrases along the edges (in white) but it's all in Japanese. The over all effect of the poster is a sort of colorful collage type feel.
