History:
The words ‘West Germany’ are a big clue that your plate was made for export between 1949, when East and West Germany were formed, and 1990, when the country was reunified. The crown mark was used by Josef Kuba Works of Wiesau, Bavaria, Germany. Kuba’s factory was founded in Carlsbad, Bohemia (now in the Czech Republic) in 1900, but was reestablished in West Germany in 1947. Plates decorated like yours lost popularity by the end of the 1950s, so it’s likely your plate is about 50 years old.
