The "Just Judges" may contain portraits of Jan and Hubert as the third and fourth Judges on horseback. The evidence based on the similarity of one of the figures to Jan's 1433 "Portrait of a Man", now in the National Gallery, London, generally thought to be a self-portrait. The second, closer, figure is thought to be Hubert, because of facial similarity to Jan. Although the judge in the Ghent panel appears to be younger than the sitter in the London painting, they wear similar chaperons with the cornette tightly bound around the bourrelet. The judges in the Ghent panel became the basis for a number of later portraits of the brothers, including that of Dominicus Lampsonius.
