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).
I just noticed that if you click on his Twitter picture (appearing at DC) it enlarges a bit and there is script that says it is the same tattoo that appears in the close up of the MySpace picture (at wagist).
Yes, because if you used Photoshop, Fireworks, or another imaging program to flip the photo horizontally (turn it into a mirror image), you would go from a left shoulder to a right shoulder . . . but you would also cause the word 'Nana' to appear as a mirror image. It's spelled correctly in the close up - which should mean the photo showing Trayvon's face was the photo that was flipped. Is the writing on Trayvon's hat mirror imaged, or does it read correctly (I'm currently working off my phone's browser)?
