a.k.a. Series One R2-D2 Mug
This is a mug shaped like R2-D2, the droid from the science fiction Star Wars films. He is a small robot with buttons and lights around his body. This is one in a set of six (including Yoda, Chewie, R2-D2, Vader, Trooper, and Boba). They are a tikified re-imagining of the drinking vessels that might be used if the Mos Eisley Cantina in Star Wars was actually a tiki bar.
