I am far too lazy to register/post on other websites, clearly a lot of people are reading this thread so let me just throw this out there...
I think people are reading way FAR into the Egyptian props. I believe these props to be used as background filler for this Ante Chamber set. Yes, there's probably going to be better designed and custom built props but these are just to add clutter to the set, etc. So for the folks on the Raider.net forum going on about how goofy some of them may look, or some of them may be based on cats like tutankhamen, they probably have nothing to do with the story, like I said, they're simply filler.
And just to clarify, these egyptian photos were not taken on a set. So anything you see in the background has nothing to do with Indiana Jones.
Oh, and one more thing. The SuperHero hold cards are for another production that has nothing to do with Indy, either. Set Decorators go into a prop house and as if they were shopping, they find what they want, place a hold card on it. Then the property department makes a list of everything that has a hold card on it, calls the production office and gives them a rental qoute for the props. Multiple productions use these props often back to back, and as you can see these dates are very close to one another, hopefully that clears that up too. Carry on
