There is this site that you can get any of rare/rad horror shirts they have printed on a back patch.. sent Shants the Frankenstein "the monster is loose" one... here is what he came up with
he had to make the back really stretchy like that because I have a huge cranium and tend to let my hair go.
Just for amusement... here is a shot of him wearing it for comparison
