British artist and illustrator (1867–1939) best known for his Art Nouveau–influenced illustrations. Original vintage signed pen and ink sketch depicting a grove of trees in front of a huge waterfall flowing over a mountain cliff on an off-white 7 x 10.25 board, signed along the bottom, “A. Rackham.” Pencil notations on reverse indicate the sketch was to be reduced in size to four inches wide, indicating it was likely to be used to illustrate a magazine story or possibly a book.
