This image is Hayter's first color print and depicts the artist's then wife, Helen Phillips, cradling their newborn son Augy.
... in San Francisco in 1940, a print, Maternity, was made in which one opaque color, orange, and two transparent colors, blue and ochre, were printed in tempera on damp paper, using silk screens to replace stencils, and finally overprinted with black in intaglio from the plate. - Stanley William Hayter, New Ways of Gravure, 1949, p. 159
