Mural, painted in 1943, was Pollock's first major commission. It was made for the entrance hall of the Manhattan duplex of Peggy Guggenheim, who donated it to the University of Iowa in the 1950s where it stayed until its 2012 arrival for conservation and study at the Getty Center. This book unveils the findings of that examination, providing a more complete picture of Pollock's process than ever before. It includes an essay by eminent Pollock scholar Ellen Landau and an introduction by comedian Steve Martin. It accompanies an exhibition of the painting on view at the J. Paul Getty Museum from March 11 through June 1, 2014.
