From 1759 onwards all masters producing furniture in Stockholm had by Royal decree to stamp or sign their furniture if they wanted to sell them on the open market. The decree was, however, apparently not always strictly observed as the cabinet-makers were on at least two later occasions reminded of their duty. In 1768 the guild of cabinet-makers found it necessary to authenticate the works of masters to prevent forgeries, by introducing a stamp of a double-entwined S within a circle, which was in use between November 1768 and June 1780.
