Since I just rewatched Harry Potter 7a in preparation for the final episode (which I'm looking forward to, though I know my ass will be numb by the end of the film), I am in a bit of a Harry Potter mindset. Hence this graphic rather tickled me. Not sure if this is the original source; I suspect not, but I could only find reposts. If you are even more amused by the design than I am—amused enough to, say, wear it on a shirt—you're in luck! Here are the shirts you seek.
