The L.L. Cook Company was a postcard company based in Milwaukee, Wisconsin. They traveled around the United States taking photos of community landmarks and producing “real photo postcards” from the 1920s through the 1960s. In the early 1960’s the company visited Washington and produced several postcards picturing city churches, schools, and other buildings of interest. To date, researchers have found the following examples of these postcards. The cards are numbered, but more randomly than other postcard sets we have found.
