I'm hoping that the jacket comes off easily and that the shirt is a complete garment...I'd prefer to display him without the jacket the way he was at the movie's opening warehouse scene.
Unless he does include the skull...then it's jacket on.
As for the foot-on-the-skull idea...I don't think I like that idea,,,it seems out of character that Indy would use ANY relic as a foot stool. I'd rather see the foot is resting upon a block from the Nazca Temple or just a rock or something. The skull should be included with an option to have it under his arm,
Something like this, maybe... (illustrated with the Medi KOTCS Indy figure...)
