This is a promo shirt for Sonic & the Secret Rings which is likely somewhat hard to come across. It was free, but only if you bought the game from Nintendo World in NYC, likely on the first day of release (as free items tend to run out quickly) It's got front& back printing, but is still somewhat plain, as promo shirts can be. The front has the specifically styled logo & the back has the main graphic for Sonic, as he is wering the magic ring and is afflicted with the infection/flame that serves as a part of the game's plot.
