Circa 1928-34, the heads of these antique glass rabbits salt and pepper shakers were manufactured by S.W. Farber, Inc. from Brooklyn, New York.  The S.W. Farber firm created various household chromium-plated metal items.  They bought  or imported glass from other companies to pair with their metal products.  The glass bodies of these shakers were imported from Czechoslovakia.

A complete set will have their original glass eyes intact.  They can be found in various colors - sometimes matching and sometimes different.  They stand about 3'' in height.  Other animals were also created, including dogs, elephants, owls, cats, and birds.  A matching sugar shaker was also made to go with each different pair of S&P shakers.
