I found these two glasses and thought I'd never in a million years be able to identify them. The only thing I was hoping for was maybe a manufacturer. Sometimes it's just about going to the right place and that place was MODish. This morning I posted this image on my blog there and by this evening I had a great lead.
Their post lead me to Libbey's historical section of their website and I just guessed a year and ta da it's on page 20 of this catalog.
