THREE DUCKS ETCHING (AKA) by Unknown Glass Company for Etchings No. 1 (Unknown Location, Operated: Unknown), c1880s Introduced
NOTE: Sid Lethbridge - The Three Ducks Etching (Beeson) has ducks amongst reeds and greenery on the shore adjacent to a body of water.
For the purposes of my research the firm that did this etching has been designated as U1 i.e. Unknown 1. They were very prolific and there are about 30 etchings that can be assigned to them.
