NOTE: Sid Lethbridge - The Stork Walking Etching (Unitts) is one of at least five related etchings showing storks in various poses. This etching shows a stork facing to the right surrounded by lush scenery very similar to that seen in the Stork Fishing etching.
For the purposes of my research the firm that did this etching has designated as U1 i.e. Unknown 1. They were very prolific and there are about 30 etchings that can be assigned to them.
