Vintage Topps Return of the Jedi Trading Cards
These were put out by Topps in 1983, and as the package says, each “wax pack” included 10 cards, 1 sticker, and 1 stick of bubble gum. They came with several different characters on the package, including Darth Vader, Luke, and an Ewok in addition to Jabba.
There were 132 cards all together (including two helpful “checklist” cards) and 33 stickers. Since there was only one sticker per pack (randomly inserted) and each sticker apparently came in two different background colors, it must have been quite a task to get all of the stickers.
You can look here for a list of all of the cards, but I’m just going to post a few to give you an idea. I don’t yet have all of the Jabba ones, but I plan to get them eventually. Each card had a photo on one side and a drawing and some text on the other. The stickers had a piece of a larger image on their reverse side, allowing you to put them together like a puzzle.
