History of Heavy Metal Shirt. Iron Maiden. Black Sabbath. Judas Priest. Mark V. Navy Diving Standard Dress. Full Jake. The History of Diving is a history of some very heavy metals. The beige shirt is unassuming, and the design is rocking. The back features three divers in full dress and the front has the History of Diving Museum’s logo. A great shirt even if you don’t like heavy metal music – it’s a favorite here at the museum!
