This folding cardboard case is covered with green leather and lined with blue velvet. The back of the case is marked: 1905. Inside the lid flap, the left end is marked in silver: THE SPECIAL. A drawing of a sword runs through the words. The right end of the flap was missing when the set was received by the Smithsonian, but originally it likely was marked with the name of the retailer. The set includes:

Schoenner was an instrument maker in Nuremberg, Germany, that particularly targeted the U.S. market. The firm held the rights to the March 17, 1903, patent, which covered the design of the pivot joint on drawing compasses. Georg Schoenner Jr. applied for the patent mentioned on the pen latches on February 4, 1904, and received it on June 14, 1904. For company history, see 1989.0305.05.
