If you’re a deadhead or a casual fan of the Grateful Dead or you are Irish or love Boston or even if you just like sweet looking t-shirts with skulls on them, this fully-licensed t-shirt is what is known in the industry as a "must-have." So buy this t-shirt, and as Jerry Garcia himself sang, "just keep truckin.'" We're not sure what that means, but we assume it includes having a good time and twenty minute guitar solos.
