This company is going wild with color variants!
Here you can choose from 4 different versions of the same Sonic/Shadow/Chris shirt.

Each one is exactly alike except the colors. You can see a line-art of Chris punching the air among lines and dots in the background, while Sonic and Shadow are both doing the jumping punch. Shadow has his name written down the side vertically...but Sonic's is a bit harder to see. (above his head) The standing Sonic is another of their plastic appliques. Which color scheme do you like best? You can bid for these on Ebay in 2008, and then again in 2010
