"Portrait of Johannes Froben". Oil on panel, 48.8 x 32.4 cm, Royal Collection, RCIN 403035. Johann Froben (1460–1527) was a noted book printer in Basel. He was a close associate of Desiderius Erasmus, whose works he published and who, for a time, was a guest at his home. Hans Holbein the Younger met Erasmus through Froben, for whom he designed many book illustrations. He may have painted the original in the early 1520s, prior to his departure for England in 1526.
