This tee is somewhat unusual in that it appears to be made of some kind of shiny or glossy fabric. It's not regular cotton tee material. It's another slogan shirt, this time with "Here comes the Boom" and "Sonic And Friends" written in letterman style thick font. It has CG art for Knuckles, Sonic & Tails quite large across the front, on a small red background. The bright CG graphic is an interesting contrast with the different fabric of the tee. Where can this be found?
