This is a liquor cocktail glass with an etch called First Love. The maker was Duncan & Miller from Pennsylvania. The etch was in production from 1935-1955. I have stared at this a bazillion times and have tried to figure out what the pattern has to do with one’s first sweetheart. The stem is interesting, but actually too ornate for my liking. I don’t think I have any other Duncan & Miller stems. Don’t know why. Check out The National Duncan Glass Society at www.duncanmiller.net if this stem appeals to you.
