In 1930 the 1896 born Josef Kuba opened a small porcelain factory with its own little decoration studio in the city of Karlsbad (today Karlovy Vary, Czech Republic). During the Second World War, the area was overrun by German forces and remained occupied until 1945. Following the end of the war, Kuba re-established his decoration business in a building on Herbstweg road in the southern part of Wiesau (Bavaria). Since then, his work was mainly based on pieces from the Porzellanfabrik Carl Schumann factory in Arzberg (Bavaria) or the Heinrich & Co. factory in Selb (Bavaria) although he occasionally used items by other manufacturers, for example Hutschenreuther or Tirschenreuth. While Kuba decorated many items in a number of different styles like Alt-Wien ("Old Vienna") or Rembrandt, he preferred to include transfer applications based on oil paintings by the French artist Jean-Honoré Fragonard that mainly depict courting couples. With a little luck, one can also still find a few items with the rarely used Ätzgold, etched gold borders.
After the death of Josef Kuba in 1972 his son Horst Kuba continued business until he decided to close in 1989. The rectangular mark shown as Image 010253-02-02 for a long time was claimed to be the only mark used during this period, however the now also shown "HK" mark was verified via Sandra Kuba.
