I'm not a huge fan of the Freakables line from Palisades, but they put several of the pre-production items up for sale on ebay, and the prices were just too good to pass up.

This first one shows a test shot of Sugar Freak with the original box that was planned with a window box.  The second photo shows another Suger Freak test shot, this one in very different colors than the final version, and with all five faces.

One of my favorite Freakables is Deep Creap, and I picked up a couple early test shots.  This one (on the right, as usual) is in very different colors than the final piece.  He also came with the other two faces, unpainted.  The third photo shows another Deep Creep, this one cast in various plastic.

This early Meat Head pre-production piece comes with all three faces, and is also in very different colors than the final production piece.
