Negatives, ca. 1905-ca. 1939, were produced by Fritz E. Bjorkman and most likely collected by Herman Blumenthal for visual research. A small number of nitrate negatives may have been produced by Bjorkman's father Herman. Photographs depict a large number of places, including New York, Ohio, Maryland, Florida, California, the U.S. Southwest, and Mexico. One particular focus of the collection is parades, including photographs of an Armistice Day parade, a Liberty Day parade, parades commemorating the second and third Liberty Loans, and a Macy's Thanksgiving Day parade. Along with many family photographs, the collection also includes photographs of monuments, memorials, buildings, canals, houses, and battleships. There are also a large number of World War I home front images. Some notable people included in the collection are: John J. Pershing, Ferdinand Foch, Theodore Roosevelt, Franklin D. Roosevelt, Al Smith, Fiorello La Guardia, William H. Taft, and Chief Oskomon. ; Fritz E. Bjorkman was an electrical engineer born in Sweden in 1892.
