What makes this illustration different than the previous one I posted (besides that it's R2-D2 only without C-3PO) is that it also acts as a color key and first in a sequence of illustrations, as designated by the color notations (and color in general) and the circled notation of R-1 at the bottom right. I think I got that explanation right...hopefully.

"Star Wars: Droids: The Adventures of R2-D2 and C-3PO" is a 1985 animated television series spin off from the original Star Wars trilogy. It focuses on the exploits of droids R2-D2 and C-3PO prior to the original 1977 Star Wars film (A New Hope). The series was produced by Nelvana on behalf of Lucasfilm and broadcast on ABC with its sister series Ewoks (as part of The Ewoks and Droids Adventure Hour). The series ran for one season of 13 half-hour episodes, followed by an hour-long special broadcast in 1986 that served as the series finale. Anthony Daniels reprised his role voicing C-3PO in the series.

Episode synopsis:

Having escaped, Mungo, C-3PO and R2-D2 once again make their way for the planet Roon, but it turns out that they have not seen the last of General Koong, a de facto governor desperate to win the support of the Empire.

Star Wars month continues on!
