Johnson moved to The Hague in 1851. On November 20, 1851, he wrote to Andrew Warner of the American Art-Union, “I am at present . . . at the Hague, where I find I am deriving much advantage from studying the splendid works of Rembrandt & a few other of the old Dutch masters, who I find are only to be seen in Holland. I shall probably continue here a good portion of the winter.” (Adapted from Hills, The Genre Painting of Eastman Johnson, pp. 40–41.)
He made free copies after Rembrandt, Van Dyke, and the contemporary Belgian painter Louis Gallait. He stayed in the Netherlands until 1855 and developed a profitable career as a portrait painter. —PH

Hills, 2022: Although John I. H. Baur owned and annotated a copy of the catalogue of Johnson's 1907 Estate Sale, he did not include this work in his own 1940 catalogue listing; he must have obtained it after publication.
