This Mecator's projection map shows existing airmail routes from around the world. The map was a gift from Henry Woodhouse, a colorful figure in early aviation history, to Benjamin B. Lipsner. Lipsner had served in the U.S. Army, where he reached the rank of captain. He assisted Major Reuben Fleet with the organization of the first regularly scheduled airmail service in May 1918. When the Post Office Department took full control in August 1918, Lisper resigned from the Army and was named first superintendent of the airmail service.
The map is inscribed by Woodhouse to Lipsner, “To Captain B. B. Lipsner, The First Superintendent of the US Air Mail, in appreciation of his pioneer work for the development of aeronautics.” The original copyright date of the map is 1919, but the routes indicated on the map reflect the post-World War II era.
