If you are in Philadelphia this month, you might want to swing by the Brave New Worlds comic store for the Sonic Generations Art Show. Starting last Friday and running through the end of December, you can come in and check out a variety of Sonic-themed pieces on display, such as the ones I've included in the gallery below.
I dig the 1930s Mickey Mouse-style Sonic as well as the dapper-as-f*ck Robotnik decked out in the finest Mobian furs. The funniest one to me, though, is Danny DeVito as Robotnik with little bits of tissue to cover the shaving nicks where his glorious mustache once lay. A couple others pieces are... disturbing... but I'm sure a few of you are into that freaky sh*t, so whatevs.
