Artworks in book form, not books about art, or art made of books. William Blake (English, 1757-1827) was among the first artists to create books with his own pictures and texts. Some artists' books have only pictures or only texts. Marcel Duchamp (French, 1887-1968) made some, beginning in the 1930s. Artists in many countries have produced them since the late 1960s, including Sol LeWitt (American, 1928-), John Baldessari (American, 1931-), Ed Ruscha (American, 1937-), and Anselm Kiefer (German, 1945-).
