Eggfans will be happy with this one! It's an all red shirt with a rather classy all-white design of the Doctor shaking a fist. It's rather stylish to present him this way, and it's also wonderful to see him alone, without any other character. This has the makings of a rare shirt. Great for Eggman Fans, no one to steal his spotlight! This is at: sonicthehedgehogmerchandise.com
This aqua tee looks similar to some others. It's got the "big group of characters layered/stacked" as the design, but adds some black spray paint spatter at the bottom with drips around the logo. You can see Sonic Tails Knuckles Shadow Silver, Cream, Amy, Blaze, Eggman & for some reason Jet, but without any other Babylon Rogue. It's a nice design, if you don't already have something similar. This is likely to be sold at FYE / adult sizes.
Here's another nice group tee. With 6 characters it's not over-loaded but you've still got fan fave Metal Sonic, plus Eggman, who rarely appears on shirts so it's good & somewhat unique to have. Shadow also appears in the 'villain row' in the back. There is another version of this shirt that is white. Available winter 2012.
This shirt uses pale colors & an odd colong structure to draw attention. It says "Don't Stop" in blocky letters up one side, with modern jumping Sonic, who's shoes, socks & gloves aren't colored at all. Since the shirt is mottled gray, this makes it look slightly unusual.
Here's another "9 faces of Sonic" this time on black, with colored backgrounds for each of the expression /portrait squares. Thought to be the 3rd one with this similar pattern of 9 designs.
