The left deck is an ‘Autex Sports’ complete. The graphic is a crazy mix of the Rob Roskopp 3 from ’85  (designed by Jim Phillips for Santa Cruz)  and Powell’s famous Ripper (by VCJ). It all looks pretty ridiculous: a violent Ripper seems to have eaten the monster and is almost strangling himself with a chain, acting all clumsy and the flames make no sense at all. The right ‘Alpha’ deck is clearly a counterfeit of Rodney Mullen’s Mutt deck from 1981, it even says ‘Mutt’.  The board was relisted on eBay, since it ‘only’ reached $200 in the first auction, but that wasn”t enough for the seller. Thanks to christopha80  for the tip and Omar for the pictures.
