Fair price?

I think this is a later iteration, a 1st issue AHI Mummy should have boots, not shoes... I think his right arm should also move across his chest, with a bandage sling holding it in place... ? That's usually disassembled. I'm sure AHI would have issued the figure with shoes (just 'cause it's yet another dopey variation) but my later one had bandage from his legs wrapped around his feet. Usually I see them barefoot. I have had two versions of the AHI Mummy, and for an average example like the one pictured, their price is top dollar. If the boots and arm were 1st issue... at least 200.
