May I add that Print Mafia would never use photoshop. Period. That's not part of their asthetic. Secondly, for anyone to think that they would blaspheme Johnny Cash with devil horns and a goatee is ludacris. Now Jesus is another story. . . . .
Well the font and the halftone remind me of PM, but PMs posters are almost always tall (12.5x27.5?) and they use the negative space in a more interesting way.
Plus, they would never use this image (cliche) It would probably be some kickass old school porn.
