This is a Pure Fucking Armageddon short sleeve XL t-shirt by Hanes. Front side is the demo tape cover of "Pure Fucking Armageddon" and back side is "RIP Øystein Aarseth aka Euronymous, 1968-1993." with two inverted crosses. I actually own one shirt of this kind. So far, I have not seen any others. This is the rarest Mayhem t-shirt that I currently own.
