This is an interesting belt with modern Sonic theme. The graphic for him is so large that you can only see a little part of his face, with some black/white checkers for the background. The result is sort of abstract.
Here is a checkered belt with Sonic's name / logo theme. The right photo is probably the same belt as the one in the left photo, but the design is kind of abstract-ified by the narrowness of the belt so its hard to really tell. It's black & white, with the logo in blue & yellowish on the sides & belt end holder strap. It costs about $25, which is rather pricy for a belt. It can be found at Gametraders in 2012.
