This is a men's/adult sizes only tee at Old Navy.
It's pretty cool! It uses the very good classic Japanese 3 point stance for Sonic & a cute neoclassic twirling Tails, who is in a fun circle in the corner. The tee is Sonic's blue color, so the only color of ink used here is white. Interestingly, they chose to fill his sock & shoe in with white as well--which looks fine, but is generally not chosen by designers for whatever reason. It spells out "Sonic" at the top in Japanese letters, but then look at all the words down the edge, and under the design. The denser characters (more lines) are whole words in Kanji...but what do they say? You can write in for credit if you know.
