This tee is likely by the same company that released a whole batch of designs into Burlington Coat Factory stores early in 2019. It's just too bad it doesn't mark the clothes with any sort of brand...
This all black tee uses the color modern Japanese Sonic logo at the top (with name spelled out below) The design is a very large forward-facing modern Sonic face (smirk version) but with 'paint drips' added for a graffiti style look, especially at the bottom. The head has a texture/color look because it is filled in (anywhere he would be blue) with lots of tiny character art of Sonic/Tails/Knuckles and Eggman.

Because this is so nice and different looking by blending many elements it really brings something new to the table for tees. A good shirt to collect...but where can you find it? It looks like it may be an adult size item too.
