This featured shaker depicts the idiom "the straw that broke the camel's back", alluding to the proverb that describes the seemingly minor or routine action that causes an unpredictably large and sudden reaction, because of the cumulative effect of small actions.
This shaker is considered by some a go with. The shakers have flat bottoms and were made in the USA in the 1940s. The set stands about 3'' high.
