Richard W. Goulding. "Wriothesley Portraits: Authentic and Reputed." Walpole Society 8 (1919–20), p. 47, no. B.ii, pl. XIII, states that the attribution to Holbein is improbable, since Holbein died in 1543, and Wriothesley wears in this miniature the same ermine-lined mantle that he wears in the Woburn Abbey portrait, representing the sitter after his election in 1545 as a Knight of the Garter.
