Love the art! Love the shirt! Congratulations, yours is one of only three designs I've chosen to announce my broniness to the world. Being a manly man (camping, hiking, pro wrestling, heavy metal, blow 'em up action movies, etc.), I've been Brony only in private, but I love the show and the fanart so much I'm no longer embarrassed by it (as long as awesome art like this exists).
I think it was on redbubble. I might have it favourited, let me see...there you go! www.redbubble.com/people/c-puf… Sadly, I can't order it, since the shipping would cost just as much as the shirt (living in Germany is a bitchXD)
