They are stem #6024 – Cellini by Fostoria. Production dates – 1938 – 1970. The interesting item is the optic, a loop optic. I thought the no optic look more ‘scalloped’, but I guess this is the same look, regardless of the name! Different in any event.
I think these are the liquour, or cocktail glasses.
I was assessing these for sale and noticed that all three of them had a production flaw that resembles a scratch in basically the exact same place on each stem. Weird. The trouble is that the flaw can be viewed through the stem. Since they are magnified they look larger than they really are.
They are in the ‘giveaway’ pile for someone to enjoy.
