This series of flowers came out of Germany. Circa 1920s-30s. They are small - standing only about 2.5 inches high. All the sets below have been found with each shaker containing the same number of holes. They are usually stamped "Germany" on the bottoms. As you can see below, each flower can be found in different colors.
Each different flower has a uniquely shaped flower pot, but they each have an orange painted ring at the top.
