Lol...My Aunt had these metal cups...I can remember a summers day in 66 and coming in from playing, my Aunt grabbed these colored cups, went to her Wards refrigerator, took out a glass pitcher of cold tap water and poured us all a cup. To this day when I am thirsty and gulp down a glass of water....that memory flashes back.
Cracker Barrel had some somewhat similar remakes a number of years back. I should have bought them.
Someday, I'll go on ebay and find me a set.
Here's another memory I had from my grandpa.
You can still get those metal cups at the VT country store catalog
