70's Green Tupperware Storage Container with Lid - 70's Tupperware - Toy Storage

This is a classic jadeite green Tupperware storage container and lid. It measures 13" long, 4" wide and 3" tall. The bottom has square shaped ridges, so I'm not sure if there originally was an ice cube tray to go with it???????? In excellent vintage shape, there is some light scratching/wear to pieces commensurate with age. Please see the pictures for details.
