Signs, circa 1973-74

"In the summer of 1973, while visiting friends in England, Evans began to experiment with a new compact camera, the Polaroid SX-70, using it to make casual portraits of his hosts, the poet Robert Lowell and his wife Lady Caroline Blackwood....later in an effort to promote the camera as a serious tool for making art, the Polaroid Corporation provided Evans and several other established artists with unlimited film, and enlargements upon request," Fineman, Walker Evans, pp. 135-136.
