The original ones i have seen are not your average garment. Some thought went into the deisgning of the shirt, maybe to make printing easier on the back. But now i see many similar prints on your basic tee. They all say the same thing for the tourist, simple 1 color prints. The retail customer i print for sells the real thing and he has to go through a California company who produces ($28.00 wholesale) them and he has a local rep. He does have some exclusive rights to certain names/locations on the back but not the garment itself. Two summers ago no one cared about these shirts, but the Soroties down South have made them a hot item for the summer. I beleive it is puff ink on them, i have only seen wihte ink though. They might use puff to make it easier to print on dark colors.
