marketing - First movie that collaborated with fast-food outlets?

In 1984, the movie Gremlins teamed up with Hardees to sell a set of LPs that came along with the movie:

Each week a different record would be sold, thus, each week, parents had to take their children to Hardees to get the latest one.

What was the first movie to team up with fast-food to do something like this? What was the product they sold?
