For your consideration, here is a rare original and authentic souvenir prop given to cast or Imagineers in 1995 who worked on the Opening of Indian Jones Adventure attraction at Disneyland. It measures about 2" wide x 4" tall x .5" depth.  It is made of a metal (pewter?) depicting the temple of the forbidden eye. It is in very good condition with minimal wear - see pics.  If you have any questions, please let me know.
