166H Bulls, silver sage glaze on the 2 hole shaker, royal blue glaze on the 3 hole. No base marks. Note that the pour holes are the eyes of the bulls. Unique I believe. The royal blue shaker was first punched with a 5 hole cursive “S” on the back indicating it is from the earliest production. Prior to firing the cursive holes were filled in and new holes made at the eyes. The pieces were then glazed and fired. The silver sage shaker does not exhibit this trait (seen through filler hole). I purchased these from a dealer in Sapulpa along with a “pair” of cats in ivory and royal blue. This is a clear example of a pair in different colors.
