I am assembling a report for school and I cannot remember if he worked solely with oils or not; and I also don't remember reading if he did or not. Does someone know?
His works include drawings, prints, watercolors, and oils. Besides pencil and charcoal, he used pastel, watercolor, and gouache, as well as the various printing processes: drypoint, etching, aquatint, monotype, lithograph, and even woodcut.
