Helen Frankenthaler (1928-2011) has long been recognised as one of the great American artists of the twentieth century. Painted on 21st Street: Helen Frankenthaler from 1950 to 1959, a beautifully illustrated new book devoted to Frankenthaler's paintings from the 1950s, brings together nearly thirty paintings, including important works from Frankenthaler's estate. A new essay by John Elderfield and important historical texts by the poet and art critic Frank O'Hara (1960) and former Rose Art Museum director Carl Belz (1981) shed light on the work and a new, full chronology of Frankenthaler's life and work in the 1950s, draws upon previously inaccessible archival sources. The stunning colourplates are supplemented by some 75 additional illustrations, including several never-before-seen documentary images. Published to accompany an exhibition held at Gagosian Gallery, New York, in Spring 2013, this lavish volume is the first to be published since this acclaimed abstract painter's death.
