Oil on canvas; 75.6 x 64.5 x 3.2cm (29 3/4 x 25 3/8 x 1 1/4"). National Portrait Gallery, Smithsonian Institution, Washington, DC.
As Rembrandt Peale recalled later,
the hour [Washington] appointed was 7 o'clock in the morning. I was up before daylight, putting everything in the best condition for the sitting with which I was to be honored, but could scarcely mix my colors, and was conscious that my anxiety would overpower me and that I should fail in my purpose unless my father would agree to take a canvas alongside me and thus give me an assurance that the sittings would not be unprofitable, by affording the double chance for a likeness. This had the effect to calm my nerves, and I enjoyed the rare advantage of studying the desired countenance whilst in familiar conversation with my father.
