In 2003 the sitter was identified as Hans Schwarzwaldt (1513-1575) based on a resemblance to the subject of another portrait miniature painted by Holbein in 1543. That portrait, with the inscription ANNO ETATIS // SVÆ 24 1543, indicating that the sitter was twenty-four in 1543 (and therefore born circa 1519), was looted from the Danzig Museum (now the Gdańsk National Museum) by the German occupation forces in 1943, then claimed by the Soviet Union’s Red Army as spoils of war in 1945. The portrait, one of a number of works of art subject to restitution requests by the Polish government, is located at the Pushkin State Museum of Fine Arts, Moscow. In 2016 the young man was identified as Gregory Cromwell (c.1520–1551), son of Thomas Cromwell, Earl of Essex, chief minister to Henry VIII.
