Rosenthal Marks used for the American Market
During the period between the
two World Wars (1925 to circa 1941) Rosenthal porcelain was
distributed in the United States by Rosenthal China Corporation
based in New York.
European manufactured porcelain for the American market was marked with
a cartouche placed over the original production mark. The original
mark is often visible beneath the cartouche when placed under a
strong light. There are also examples where the cartouche didn't
completely cover the original markings.
The cartouche was required to
meet the U.S. Government Import Regulations which required all
imported goods to be clearly marked with their country of origin.
Goods privately imported (e.g. Service Personnel who had been
stationed overseas) often failed to comply.
