Fans are going to go wild over this one. Featuring the group’s electrifying leopard center chest, this new Def Leppard addition pays homage to the boys’ third studio album “Pyromania.” An honorable mention as being the first release to feature Phil Collen after the departure of Pete Willis, and shifting away from the group’s traditional heavy metal sound to a more radio-friendly offering. Ultimately charting No. 2 and bringing them into mainstream success, “Pyromania” and Def Leppard’s subsequent world tour hits the back of this ringer tee featuring the album’s name in block letters with both an American and British flag to tribute the crew.
