Downtown Baltimore, aerial view with harbor, piers and power plant in foreground, 1937

The collection consists of one box with five folders containing 17 photoprints made ca. 1935-1940 by Clarence Beckett of the Maryland National Guard 104th Photo Section of the 29th Division Aviation. The images are aerial views of Maryland, including the inner harbor and downtown Baltimore, the U.S. Naval Academy in Annapolis, and Fort McHenry. There are many aerial views of sites affected by flooding along the Potomac River in March 1936, including Hancock, Big Pool, Williamsport, and Point of Rocks, Maryland.

Some images show planes including a Pan American Airlines x14714 plane, a Martin 130 series seaplane and prototype of the "China Clipper" used by Pan Am. There are also pictures of an unidentified monoplane after crashing in a field in August 1940.
