A closely related portrait-silhouette of the Empress Maria Theresa, and its pendant depicting her husband, later Emperor Francis II, Francis I of Austria wearing The Order of the Golden Fleece and The Cross of the Military order of Maria Theresa, are at Waddesdon Manor, Buckinghamshire (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.

A further portrait medallion of the Empress, with its pendant, was sold from the de Trafford Collection in these Rooms, 3 March 1994, lot 1.
