Although Katz considers the large works to be his major productions, small-scale paintings are the underpinning of his work, revealing his initial passion for a subject -- a love at first sight before it has fully matured. While his big paintings are akin to a public performance, the small paintings are rehearsals that reveal not only how he works but more importantly why he is interested in a particular subject. This volume focuses on the achievement and significance of Katz's small paintings.
