Q: Can you give me some information about the marks on this plate? How old is it?
A: Christian Heinrich Schumann had a factory in Arzberg, Germany, from 1876 to 1879. From 1881 to 1892 he was in business as Porzellanfabrik Schumann & Riess. Schumann designated his son, Carl, as the heir to the factory but when Schumann died in 1884, he was too young so his mother ran the factory. It was renamed Porzellanfabrik Carl Schumann G.m.b.H. & Co. K.G. in 1892, when Carl was 21 years old. He took over running the business in 1896. The company was incorporated in 1923 and became Porzellanfabrik Carl Schumann A.G. Carl Schumann II took over after his father died in 1926. The factory closed in 1994. The company used this mark from 1960 to 1970. The second mark was used by the importer, Ebeling & Reuss. That company started in 1886 as Zeh, Ebeling & Reuss Co. In 1900, Zeh left and it became Ebeling & Reuss. The company moved to Devon, Pennsylvania. Porcelain, earthenware, and other items were imported from Germany, Czechoslovakia, and other European countries. Ebeling & Reuss registered this mark in 1956. It was used until 1960.
