Really nice original art. Many of the cups were recolored and used for the Empire Strikes Back series released in 1981. The boxes are from the original Star Wars series. The cups are a mix from both series.
We always had Dixie cups in a little dispenser in the bathroom—wasteful, sure, but so much more civilized.
