Decorate your walls with even more great posters!
The top three here came out with their respective games. Each one is fairly large. The first Sonic 1 image is shared by a calander. It's a real classic look, with stock art Sonic on checkered ground.
Riders uses the familiar "Try to Keep Up!" slogan along with the catchphrase "Who needs wheels when you've got air?" and then shows screens from the game at the bottom.
The Rivals poster is really nice, not like a 'promo style' like the Riders one. It's just a nice big art of Sonic, Shadow and Knuckles. The little bit at the bottom says "Sonic Team"
The last photo is a collection of yet more posters that came with STC. (they really gave away a lot of stuff!) It ranges from the usual STC style Triangle-head Sonic to interestingly shaded Knuckles and semi-rendered Tails. The swimming Sonic one says "Underwater Sonic".
