I have the image from the Joker & Cat Adjustable Cap on a t-shirt and my one god-daughter refers to it as the 'scary cat' without making any mention of the Joker which might be some cause for concern. Produced from man-made materials, the one size fits most Joker & Cat Adjustable Cap has the Clown Prince of Crime, Batman, and a very friendly looking kitty-meow meow...that is if you are in Wonderland. Say, where the hell is the Mad Hatter? Joker is moving in on his motif!
