Original Wax Sculpting for Unproduced Death Star Emperor: This 4:1 wax sculpting representing the Emperor sitting on his throne was made for the never-produced "Throne Room" addition to the Micro Collection's Death Star World playsets. It's sculpted entirely of a special blend of wax, and would have served as the master from which "4-up" hardcopies and, eventually, metal miniatures would have been manufactured.

Here's the back. Quite a few figures are known to have been in development for the ROTJ addition to Death Star World, including at least one other Emperor.
