Here's a shirt that was actually a prize at the Summer of Sonic event!
This Sonic Heroes theme tee was a give-away item there. As you can see it doesn't have anything on the front or back (somewhat unusual) but it uses the 3 stripes and logo on both of the sleeves. It's a good quality shirt with good printing too, it's not cheap just because it was a prize. This was also a pre-order give-away prize shirt at the store GAME, if you pre ordered Heroes there, you'd get this. Added info by JenHedgehog
