A series of photographs were taken on February 28, 1957, at an unidentified laboratory involving product testing. This technician appears to be monitoring the strength of note-size paper using the Elmendorf Paper Tester. Manufactured by the Thwing Instrument Co. of Philadelphia, the arrow on the paper tester is pointing at 30 on the scale. Photograph ordered by Merchandising Factors, Seattle.
