Hi guys,
Thank you all for the kind words.
This piece was indeed originally owned by John Coppinger, who sculpted Jabba for the film. It is an original foam latex test casting of the face, which has remained in excellent condition over the years. The eyes are original production components as well, with fiberglass inners covered by thick vac formed outers.
The original Jabba puppet was scrapped (with the exception of his eyes, as noted) so this is the only original reference to the sculpt at this point.
The piece really transformed in having the display made, as without the proper shape it is just a large, floppy piece of foam rubber. Brian and Tom did a great job on this. As this piece is one in my personal collection, it is not being sold.
Best,
Brandon
