This is the awesome personal Aquaman Shrine of F.O.A.M.er Ben Holcomb, author of the definitive Mego tome, Mego 8" Super-Heroes: World's Greatest Toys. Click to see a closer look!
I recognized all the figures but one, the prototype-looking piece on the bottom right (standing between the Brave and the Bold Aquaman and the Sword of Atlantis figure). I asked Ben what that piece is, and here's what he said:
"I believe it's actually a 'Production Sample' of Sea Spear Aquaman from The Brave and The Bold, created from a prototype. In other words, it's a cast of the final design, but utilizes test plastic. I'm guessing it's a sample that was generated for client approval, since it's marked ('P4'), which would then have to be returned to the factory. I got it from a guy in Hong Kong, who presumably has access to the factory.
I really like the actual toy, so I was happy to add the Sample to my shelf. Love me some Aquaman!"
Me too, Ben...but then you already knew that. Great collection, thanks for sharing!
