A tee with a fun new idea for 2020...
But where is it sold? This mottled gray tee brings a new idea to the table: fun pocket design. The shirt's single pocket has a black/white checker race flag all-over theme, with full color modern logo in the middle. Then, stamped as if they are inside the pocket, are Sonic & Tails. Sonic is shown in front of him, and, is that a new stock art? It could be a new one for 2020, where he is faced foward. (Pocket obscures the rest of what he's doing) the Tails looks like the normal 'hand out gesture' to the side Tails, but it fits in nicely here.
Do write in for credit if you know where this can be found.
