Anchor Hocking Ruby Red Glass Cups

This is an Anchor Hocking Ruby Red glassware cup in the smooth pattern. These were made from the 1930's to the 1960's. - Picture taken on a lite box as they are very dark ruby red color. I have 2 like this and 2 in an even darker ruby color which I think are earlier production.
- This one is circa 1950's -- Coffee or tea cups - 3 1/2" rim diameter.
