In the early 1970s, armed with his 'toy' Polaroid SX-70, Evans returned to photographing favorite themes, including, as in lot 108, roadside signage. In total, he made over 2,650 images in two years. Asked what interested him about the camera, Evans replied:
'I took it as a kind of a challenge...I feel that no-one should touch a Polaroid until he's over sixty...It reduces everything to your brains and taste...You really have to know something before you dare point it anywhere. (Rosenheim, Walker Evans: Polaroids, p. 6)
Evans and the Polaroid company had a business agreement whereby he received free film. The company also gave him the option, as here, to produce color enlargements from the prints.
