Tupperware Vintage Luncheon Plates 8x8 Retro Stackable Made in USA Set of 2

Bundle of two, vintage, 8x8 inch, plastic, stacking luncheon plates by Tupperware in orange and avocado green. Plates have a lip on them so food doesn't slide off. Made in the USA. Based on the color scheme I would say these are from the1970s. Each plate shows scratched from utensils. The orange plate has more of a dome on the food portion than the green plate. Both plates are in usable, pre-owned, vintage condition with signs of wear.
