Earnshaw inspecting oyster cargo aboard boat in Baltimore Harbor, 1914-1915

The collection is housed in one box with four folders containing 15 photographic prints dated 1914-1915. The photographs show early 20th century food industries in Baltimore City. There are scenes of workers processing and canning oysters at the R. E. Roberts Company, workers processing spinach, and storage apparatus in the Pompeian Olive Oil Company album with workers dispensing oil into containers. At several of these sites, inspections are underway by United States Department of Agriculture Pure Food Inspector John F. Earnshaw. All photographs are captioned "U.S.D.A. photo by A. J. Olmstead" and dated; some have subject identification.
