Vintage Jabba the Hutt Bookmark by Random House
Produced in 1983, these were part of a set of 16 bookmarks featuring various characters from Return of the Jedi. I’m not sure if they were all sold as a set, but I imagine so. Most of them are quite well done and very colorful as well. The Jabba-related ones are Jabba, Leia as Boushh, and Skiff Guard Lando. I have all but two of these (missing Han and Boba Fett) and I really like the art style overall, although Leia looks a little off.
