I've always liked the Star Wars drinking glasses released for each movie through Burger King. The glasses for Return of the Jedi were no exception, except in one regard. I lived in Massachusetts, so when the glasses were issued, we were the only state that received ours as plastic rather than glass. Apparently this was out of safety concerns. The designs on the plastic versions were the same as on the glass, but seemed lacking because of the nature of their make-up. I have a full set in plastic, but yet to pick them up in actual glass.
There were four designs:
Luke Skywalker, also featuring the Emperor, his minions, and Darth Vader.
Han with Luke, Jabba's Sail Barge and the Sarlacc.
Jabba the Hutt, Princess Leia and the Max Rebo Band.
The ewoks with C-3PO and R2-D2.
