“The Danish rococo bureau with the Lichtenberg coat of arms on the top piece and the four accompanying chests of drawers are without any kind of cabinetmaker signature, however, there is much evidence that both the bureau and the four chests of drawers were made by the Copenhagen court cabinetmaker Mathias Ortmann (master 1727, died 1757). The chests of drawers are numbered on the back with painted black numbers no.1 to no.4 and the bureau no.5.”
