Official crewneck, one of 3 in existence. One of those belongs to Neil himself, the other belongs to the guy who made them. There was a handful of shirts and longsleeves made too, but this is probably the only crewneck version one will ever see online.
Insanely high quality print as well. Cut tag on the garment, fits somewhere between L and XL but closer to an XL. Hand-screened as well.
