Albert Kahn and John Schurman examining "Victory Sash" window

View of architect Albert Kahn and John Schurman examining a "Victory Sash" window, a steel-saving factory window. Typed on back: "John Schurman, member of the Albert Kahn organization of Architects and Engineers and developer of "Victory Sash," the new steel-saving factory window, shows Albert Kahn how sections are held together by a small metal strip. To help the war effort, Kahn and Schurman are waiving patent rights to the development, thus making it available to the entire war construction industry."
