Found these orange cups designed by one of the greatest, Massimo Vignelli for Heller. Very popular in the 70s, the dinnerware are super practical because it's stackable. I've seen a few pop up at the thrifts from time to time but they're usually in that awful green color so I don't even bother. Now, if it was a dinnerware set in yellow, orange or white, I'll scoop it up in a heartbeat. DWR is selling a set for $60 if you can't wait to get your hands on some.
