Finally, Helmar also released two separate pillow cases that are considered related to the S74 Silks: the S110. The only difference between the two Pillow Cases is the upper left player. One has Marty O’Tolle, the other Walter Johnson . Both the S81 Silks and S110's were distributed one year after the S74 Silks in 1912, and are highly collectible, and very desirable.
