I'm surprised that I don't trip over mint boxed sets of Federal Glassware all of the time, considering the plant was here in Columbus.
Lets open the box and gaze at the goodies with-in! Ooooh, Ahhhhhh!
Hmmm, I wonder what the patter name may be? Lets look at the rad sticker (it's kind-a googie).

Here is a closer look. Looks more like a sun bursty type of pattern to me.
I'm guessing that there were made in the 1970's, based on the "smoked" glass.
