Burger King has had a long history with Star Wars starting with the original trilogy. Aside from the glasses below, they also had a series of great posters for Star Wars. There's something so 70s about their style that grabs my attention and they still look good even today. Competitor Burger Chef had a series of 12 plastic tumblers, if I remember.

BK did another promo for Empire where you got a sticker book and each kid's meal came with a packet of stickers to collect to make movie scenes in the book. If you grew up in the 70s/80s you've probably seen similar collectible sticker books made by Topps.

If you were lucky enough to live in Massachusetts like me, you weren't able to get a complete set of the BK glasses because state law prohibited restaurants from giving out glasses. What was really annoying was this was decided sometime between 1980 and 1983, which meant you got glasses for the first two movies and tumblers for the last one! This is something that has since been rectified thanks to Ebay and yard sales.
