"Santa Claus, measuring twenty-eight by twenty-two inches, is a volume in keeping with Calder’s current interest in monumental works. Increased scale does not mean increased labor on his graphics any more than on his sculpture. The publisher prepared huge waxed plates, and Calder incised them with a rough tool, he says, in a few hours. The nine etchings, with their shaggy outlines, are related in style to the illustrations in his earliest books, but the former are far more original."
