Beautiful 1930's Vitros
Company name: Tri-Lite.
As far as collector's names, I think the top right here is a Superior.
I started to say all three were Superiors but I'm not so sure. I think we might have a Buttermilk on the left, maybe on the bottom also, but do wait for someone who actually knows to chime in.
