A real special deck!
This is a Skateboard Deck that is likely to be one of a kind. (So, it doesn't land on 'high end' or anything) It is actually the top prize for a contest called "Sonic Generations of Skate" that was held in 2013.

The contest helped to advertise Sonic Generations and also Sonic Lost World, which was out around that time. The board here was for the first place winner. It is made even more special because it has an autograph of the famous skateboarder Tony Hawk there near Sonic's hand. The board is mostly green/comic book style radiating lines & has CG Sonic in the center. He's posed as if leaping over something with one hand down.
As with all "Trophy Room" type things that are 1-offs, this can't really be collected, but it should certainly be looked at and archived here like this. Very interesting.
