Charles E. Burchfield (1893-1967), Dusk, ca. 1926; watercolor and gouache on paper, 17 1/2 x 30 inches; Image from the Burchfield Penney Art Center Archives.
All day on the “Fading Winter Sun” (1917, 36 x 48). The work did not go very well - all the time I felt that I was not calm enough in my mind for real concentration on such a work at this time, and that I ought not be doing it; rather some mechanical work would be better.
