Original 1947 AP wire photo showing Oakland inventor E.H. Hebern with an early model of his mechanical coding and decoding machine. Hebern filed claims totaling more than fifty million dollars against the United States armed forces, alleging infringement of his patents. The caption is printed directly on the photo. Measures approximately 6½x8⅜ inches. AP stamp on the back. Note the tape on the corners, areas of emulsion loss and typical newsroom/archive wear. Came from the archive of a Pittsburgh-area newspaper.
