The Punisher is a great comic hero.  No special powers, unless bad attitude is a power.  Started in great tragedy (family gunned down in front of him by gangsters).  Great logo.  Lots of guns.  Hunted by the authorities.  What's not to like?

The Punisher is also the comic book hero most abused by the movie industry.  First by Dolph Lundgren in 1989  (from beginning Frank used modern assault rifles; why then in the movie would he run around with a circa 1922 Thompson sub machine gun???) then by Thomas Jane in 2004 (the Punisher should never be played by a pretty boy.  Sorry girls).  He was treated most fairly by Ray Stephenson in Punisher War Zone, but by then the damage was done.  

This shirt rules.  You can't see it in the image, but the ink is very thick and rubbery and there are little Punisher logo's molded into the image.  That's why it's called crystallized.

I'm not going to link it, as it seems kind of far off topic (or rather, very Hot Topic), but apparently punisher.com is some kind of gothic web site.
