Here's the retail display poster for "Sonic Mega Collection" on the Gamecube.
It's a lively looking poster with nice big modern art for Sonic, Knuckles & Tails in a star ring. The Knuckles art is a seldom used profile type one. It has a headline, and the game's logo in Japanese. The background is a collage of game box art, to represent all the games in the collection.
The bottom of the poster has a screen shot and game title for each game in the compilation. There's only a minimum of description, and a release date at the bottom. This poster is packed with colorful Sonic content.
