This Hypercolor (but not like officially Hypercolor brand) T-shirt has wardrobe-changing penguins! Subscripted 1990 and on a Jerzees tee.
I have randomly had this shirt several times over the years of Reware Vintage, and each one magically still worked when I got it. Crazy, since most of the other Hypercolor shirts I've had no longer worked! Either this ink was just indestructible, or by chance none of the owners of these shirts ever accidentally put them in the dryer, who knows. Either way, very fun shirt! Maybe I'll run into another one again soon.
