Mid-Century Space Age Ingrid Chicago Multicolor Stacking Picnic Cups Set of 5

This is a set of five Ingrid Chicago cups in red, blue, white, yellow and green. They stack easily and feature a large handle. 4.75" L x 3.2" W x 4" H In good preowned condition. Set shows wear that is consistent with age and use. Some scratching and scuffing as to be expected. A few cups had a sticker price tag on them and have remnants of a sticky film. I tried my best to remove it. This is most prominent on the yellow cup.
