Bryson Burroughs and Harry B. Wehle. "The Michael Friedsam Collection: Paintings." Metropolitan Museum of Art Bulletin 27, section 2 (November 1932), pp. 26–28, ill., identify it tentatively as a self-portrait; observe that the type of the signature indicates that the painting dates after 1516.

Harry B. Wehle and Margaretta Salinger. The Metropolitan Museum of Art: A Catalogue of Early Flemish, Dutch and German Paintings. New York, 1947, pp. 141–42, ill., comment that "it has not the look of a self-portrait," suggesting, nevertheless, that the monogram on the hat probably stands for "Ioannes Malbodius".
Erik Larsen. Les primitifs flamands au Musée Metropolitain de New York. Utrecht, 1960, pp. 88–89, 130, fig. 32, doubts it is a self-portrait; suggests that the monogram on the sitter's hat may indicate that he was guild doyen for the year, having drawn the winning wax ball marked with J M for "Jesus Maria" from the traditional guild lottery.
H. Pauwels, H. R. Hoetink, and S. Herzog. Jean Gossaert dit Mabuse. Exh. cat., Museum Boijmans Van Beuningen. [Bruges], , pp. 65–66, no. 4, ill., states that the sitter bears no resemblance to the portraits of Gossart engraved by Hondius, Wiericz and Galle, all of which derive from the same prototype; finds it credible that the initials on the hat might relate to guild status as explained in Ref. Larsen 1960.
Sadja Jacob Herzog. "Jan Gossart, called Mabuse (ca. 1478–1532): A Study of his Chronology with a Catalogue of his Works." PhD diss., Bryn Mawr College, 1968, vol. 2, pp. 238–39, no. 14; vol. 3, fig. 18, based on the vertical format, crowded subject, expressionless face, and dark background, places this portrait with Gossaert's early portraits, before about 1516; the latinized signature, however, suggests to her that the portrait cannot date much earlier than 1516.
Lorne Campbell. Unpublished text for MMA Bulletin. 1981, tentatively dates this portrait to the 1520s; believes the letters on the sitter's hat are likely to stand for "Iesus Maria" and to be a mark of the sitter's piety.
Guy Bauman. "Early Flemish Portraits, 1425–1525." Metropolitan Museum of Art Bulletin 43 (Spring 1986), pp. 42, 48, ill. (color), places it during the first half of the 1520's and believes the letters on the hat ornament are most likely an abbreviation for "the common Christian invocation 'Ihesus Maria'"; sees the portrait as a conscious revival of Eyckian models such as Jan's "Tymotheos" of 1432 [National Gallery, London].
