Rosenthal porcelain was founded in 1879 in Schloss (castle) Erkersreuth, Upper Franconia, Bavaria as the Porzellanfabrik Phillip Rosenthal & Co. Rosenthal has survived two World Wars and a Great Depression and continues today to produce fine quality porcelain, the company now operating for over 130 years. Phillip Rosenthal opened his first factory in 1891 and the first world exposition of his products was in 1900, this Rosenthal China Plate produced in the year 1915. The original design painted by Ludwig Zubusch (German 1861 - 1927) to commemorate The Red Cross's and the Patriotic Women's Association's assistance during WW1, little did they know at the time that the War would grind on for almost another four years.
While Porcelain is virtually impervious to damage from heat light and water, but is prone to breakage and chipping from improper storage or display. Plates like this should not be displayed using expanding wire hangers, which will cause chipping and staining. In terms of value these Red Cross plates now sell at auction in the $100.00- $145.00 range.
