Conference Building, Navy Yard, Portsmouth, N.H.
This postcard is made of actual leather, which was apparently something of a novelty back in the day. It’s still possible to find early postcards made out of things like wood and aluminum.
Pictured is the conference building in the Portsmouth Navy Yard where the Treaty of Portsmouth was signed on September 5, 1905, bringing an end to the Russo-Japanese War.
This is one of four leather postcards that I own that were addressed to Miss Grace Hoare of Lowell, Massachusetts, and which I picked up during a vacation in New England. It is postmarked July 20, 1907, but was apparently manufactured prior to March of 1907, when postcards with divided backs became legal in the United States.
