Back in the day, if you went to Burger King when one of the Original Star Wars movies were premiering, you could snag one of the many collectible glasses that were offered at the time.
My family had a pile of these but, as what usually happens, many of them broke over the course of years of kids knocking them over, washing them and treating them like they are just glasses instead of pieces of art!
I only have these two left but they are fine examples of the kind of premium you could get back then.
