This the iconic Def Leppard logo. The design features the band's logo alongside a targeting reticle, which is the signature artwork from their 1983 multi-platinum album, Pyromania. This specific pin is a vintage holographic (or prism) "flicker" badge. These were incredibly popular in the 1980s, often sold in vending machines or at record stores. The holographic effect gives the background that fractured, "shattered glass" look in shades of blue and orange.
