Here's a series of prototype Star Wars character rings that were created by J.A.P. Studio. These were actually developed back in the late '90s to commemorate the 20th Anniversary of Star Wars, but apparently they were never released. I like how they designed some for the Rancor, Ackbar, and Bib Fortuna. For those of you who are into the the whole big bulky Star Wars rings thing… sorry you can't purchase these.
