Do you remember the official Sonic Toaster?
The Sega Shop took pre-orders on it to get it made in a Chinese factory. It appears here on Gear at the Housewares pages. It uses a die cut metal plate to 'burn' (or darken) a Sonic face onto a piece of toast. The toaster was a pretty popular item...but the Sega Shop itself seems to have gotten carried away by it.
They've gotten so carried away, that they created this entire tee to celebrate the fact that you can make Sonic toast. By altering the 'finger waving' classic Sonic stock art, they use a piece of stamped toast to cover up the finger...thus making it look like he's holding the slice. There is (oddly enough) a mug with this exact same theme. This is a 2019 item.
