They only made 13 episodes for the series, which aired on ABC and was created by George Lucas.  This is a one of a kind cel, used and sceen in one of those episodes!  

Star Wars: Droids: The Adventures of R2-D2 and C-3PO (later released on DVD in 2004 as Star Wars Animated Adventures: Droids) is an animated television series which originally aired in 1985, that features the exploits of R2-D2 and C-3PO, the droids who have appeared in all eight live-action Star Wars films. 

The cel is placed in front of a copy reproduction background for display purposes.  I added a mat and bag to make it easy to display in your home or office, or to place in a frame of your choosing!  

Let me know if you have any questions.
