Another interesting bit of ILM film up for auction. The original ESB emperor, with a bit of camera slate apparently showing the tv monitor the footage was rephotographed off of to get the hologram look.

I bought one of the vista vision film frames he had up for auction and I'm a watching a few more. I think there are a few buyers who are sniping (buying at the last second) his stuff so if theres something you want you'll have to spend some money on a high early bid. You could go broke on all his stuff though its so tempting.
