At first I thought it was a Sonic the Hedgehog themed t-shirt based on one of the characters from Sonic Riders who looks like a hawk.
Turns out it’s actually a Tony Hawk T-shirt. Hmmmm, seems the designers might have used the Sonic Team log as an inspiration for this.
There is also the Sonic & Knuckles game that uses this type of logo as well.
Hmmm, Not very original really. I do like it if it is a homage, but I wouldn’t buy it personally.
