Not unless somebody reversed the photo in an image processing application. The large tattoo in the MySpace photo appears to be on a right upper arm, not a left upper arm, doesn't it?
Hmmm...interesting. The close up from MySpace is a right arm. The tattoo from his second Twitter account is on his (it’s definitely Martin) left arm. The tattoos do appear to be the same though (the word written above the tattoo; it’s even sloped the same way).
Unless he took the picture himself and it's an image from a mirror. I've seen people post pictures on Face Book that they've taken of themselves in a mirror to get the angle they want. Just a thought....
