I bought these online recently – very pretty.  I’d never seen the etch in real life before.  Looks like lace.

Although Tiffin isn’t my ‘go to’ company – that seems to be Heisey – they did make beautiful glass.

These pretty stems were made over a long time span – 1941-1966.  The blank is #17392.

These are teensy weensy wine glasses, with a 2 ounce capacity.  No one I know uses these for wine!

Have a look at the Tiffin Glass Museum website.
