This catalogue was published on the occasion of the exhibition "Giving Up One's Mark: Helen Frankenthaler in the 1960s and 1970s," which was on view at the Albright-Knox Art Gallery from November 9, 2014 to February 15, 2015. "Giving Up One's Mark: Helen Frankenthaler in the 1960s and 1970s" explores the artist’s development during the 1960s and 1970s, a period that marks her transition from oil to acrylic paint, and from gestural abstraction to robust images of consolidated color and tonal nuance. It contains an in-depth essay by Chief Curator Emeritus Douglas Dreishpoon, which draws on material from previously unpublished transcripts of informal sessions Frankenthaler hosted at various colleges and universities during the 1960s and 1970s, and is accompanied by a selected chronology of the artist’s life during the years covered by the exhibition, illustrations of all exhibited works by Frankenthaler, and numerous archival photographs from the era.
