Moeller designed this set for Goebel in 1926. It is impressed on the bottom with the oldest Goebel crown logo and impressed P499. Like many Goebel animal sets from this period you can find them colored in orange, green, or yellow. Each shaker has 7 pour holes; therefore, it's debatable whether they belong together as a pair or more likely are suppose to be paired with the large cat (P498) which was also created in the same year by Goebel.
