The Detailed Notes are luxury notecards that feature a striking close-up of a great artwork on the front, and the entire artwork on the back. Each set is housed in a presentation-quality box. This set, Audubon's Feathers, reproduces details of four exquisite hand-colored plates from John James Audubon's Birds of America (1827-38): the American flamingo, the greater prairie chicken, the great gray owl, and the black-billed magpie.
