I found this on a private site from England. The collector boasted numerouse cartoon cells from several popular franchises,including "Back to the Future" cartoon cells.
The Droids cartoon came out in the mid 1980's. There were only five or six episodes...Boba Fett made an appearance...not to be confused with the Star Wars Hoiday Special. Ths was a completely different cartoon seies focusing on R2D2 and C-3PO. Stewart Copeland(the drummer for The Police)created the soundtrack :)
I asked for a cartoon cell of C-3PO but the site owner stalled because I think they knew the real value of what I was asking for. How these items come into some peoples possession,I don't know. Be careful folks,there's a lot of pirates out there.
Anyway,I did manage to scalliwager a really nice "Droid's" cartoon cell along with some nice artists sketches of C-3PO :)
