"Franz Kline was a squat, muscular man with powerful arms, a thin mustache and expressive, sloping eyebrows gathered at the center of his forehead. 'Painters seldom spoke to each other about art,' my father [ Philip Guston ] said; but once, in an easy and light bar conversation, Kline offered this: 'The real thing about creating is to have the capacity to be embarrassed.' And he [Kline] gave one of the better definitions of painting: 'Painting,' Franz said, 'is like hand-stuffing a mattress.'"
