The Museum Replicas Marvel Comics Iron Man Helmet is designed from Iron Man’s second appearance in Tales of Suspense No.40. This helmet is a fantastic and extremely accurate reproduction of the revised helmet Tony first wore in TOS No. 40. Iron Man, the Superhero indentify of wealthy industrialist Tony Stark, is committed to fighting every menace that faces free men and women everywhere. Unknown to all but his closest friends, the chest plate of Iron Man's Armor contains a mechanism that keeps Tony's damaged heart beating. Without its electrical charge, Tony might not survive.
