An identical pair of portrait silhouettes of the Emperor Francis II, Francis I of Austria (1768-1835) and the Empress Maria Theresia (1772-1807) are at Waddesdon (see T. Hodgkinson The James A. de Rothschild Collection at Waddesdon Manor, Sculpture, London 1970, nos. 44-45). As T. Hodgkinson concluded, the portraits probably date from 1792, when Francis I became Emperor, as only then was he entitled to wear the insignia of Grand Master of the Order of Maria Theresa. Maria Theresa of Sicily was the Emperor's second wife whom he married in 1790.
