The Australian firm Barsony Ceramics produced lamps, as well as other items, that are today considered to be the very essence of mid-century design. The factory in Guildford was active from the early '50s until the early '70s, and was operated by George and Jean Barsony. While other colors were offered, Barsony is best known for the popular black finish applied to the majority of their products. Scarce in the U.S. as they don't appear to have been imported.
