Heinrich Hoffman/ Schlevogt Salt.

This is a 6.5cm. uranium glass salt with an intaglio horse head by Heinrich Hoffman later Hoffman-Schlevogt, shown in their 1939 catalogue as number 1009/2162/6.5cm. Hoffman worked in Paris in the early 20th. century and sent his designs to Bohemia/Czechoslovakia for manufacture. Being uranium I think this is probably an earlier piece. Many thanks to the opensalts.us website for the information. This is an excellent source of good quality catalogue images.
