The long-awaited, three-volume catalogue raisonné of works on paper by E. W. Nay (1902–1968) offers a definitive overview of this German painter’s oeuvre that will appeal to art historians, art dealers, and art lovers alike. Comprehensive and indepth, the publica­tion brings new insights and understandings to the work of this important figure in twentieth-century abstraction. With more than six thousand watercol­ors, gouaches, and drawings, Nay’s works on paper far outnumber his oil paintings. He was a restless cre­ator who consistently put his ideas about form and color onto paper. These works embody a kind of work­ing “journal” that reveals surprising aspects of his ar­tistic method. Documenting the processes behind his artistic activities and research, Nay’s works on paper are also autonomous creations that impressively chronicle the artist’s development and vision.
