Typed on verso of duplicate photo: "Headquarters Army Air Forces, Shanghai: -- Mr. Patrick Tang, civilian accountant hired by the machine records section, 24th Statistical Control Unit of Lt. General George E. Stratemeyer's Army Air Forces, China Theater, was furnished an adding machine on which to compile his figures for the daily personnel strength report. He tried it for two days. On the third day, it was discovered that he had disconnected the adding machine and had reverted to the type of calculating machine with which he was most familiar, a Chinese abacus of the type his ancestors had used for more than four thousand years. In the background, Lt. James E. Stewart of Buffalo, New York, starts an automatic alphabetical tabulator for the last machine-run roster of China-based personnel before closing the machine records section. The return of army personnel to the United States has reduced the number still in China below the point where business machines can be economically used. (Official USAAF Photo)."

Inscription on verso: "28 Jan. 1946."
