They include images of dams, electricity generating plants, the Beal family cottage on Stoney Lake and photographs of places Anderson visited, including Orillia, Los Angeles, Peterborough, Young's Point, Sulphide, Port Hope, Muskegon (Michigan), Chicago and Trenton (Ontario).
Many of the negatives are associated with an index card, on which Anderson wrote the number of the negative, the subject of the photograph and the date it was taken. There were also a number of negatives with no associated card.
