I only know that he got it later in life. I think I read he was in his 30's when he got it. I know it's a cubist representation of the crucifixion, but the artist's name escapes me. I know he also has a tattoo on his hip/groin. A butterfly, I think. You can see it in the shower scenes on Oz. And he has something on the back of his right calf now. It looks like an outline only, but I haven't seen the whole thing. Just parts of it sticking out by his shin. I should try to find a pic again...
