Star Wars C-3PO Unreleased Head Power of the Force, 1995
Kenner developed C-3PO in their first wave of Power of the Force 2 figures. Early designs of this figure included a large round head. The figure was rejected and ultimately released with a more movie accurate sculpt. While packaging samples were produced featuring the "big head" design, but this never made it to toy shelves.
