Arthur Schuh, a Lieutenant (Junior Grade) in the United States Navy Reserve, photographed Naval activity at the U.S. Naval Frontier Base in downtown Portland from a ship in Casco Bay in 1944.

Identifiable vessels in the photograph include YP-274, a District Patrol Craft, and CS-302, the United States Coast and Geodetic Survey ship Lydonia. While stationed in Portland during World War II, Schuh captured rarely-seen images of Naval activity and locations, offering a unique glimpse into military life during the war.
