Problem is this will be made in SEA in a sweatshop amongst loads of other designs where no one will think about the slogan.
I have seen t-shirts with hitler, the twin towers, and other terrible people/event on t-shirts in Thailand that are made with no real knowledge/interest in the reference as it's something/someone from the other side of the world with no meaning to them.
Top shop designer my arse, they will comission a shitlaod of cheap logo shirts and not know what the fuck is on them till after, same as the hoodie from GAP( I think) the other month
It is supposed to be a reference to a marley song, but once unpacked and seen any intelligent store manager would/should have looked and put them straight back in the box as the obvious possible offence is there to see.
