The eye lands first on two people walking straight toward you down the middle of a slushy, snow-flecked street. Bob Dylan has his hands jammed in his jeans pockets, his shoulders hunched into a thin suede jacket that looks useless against the cold, and he leans slightly into the woman beside him. She clutches his arm with both hands, bundled in a heavy green coat and dark boots, her face half-buried and turned toward him with a small smile.

The woman is Suze Rotolo, Dylan's girlfriend, and her name appears nowhere on the sleeve. The huddling, arm-locked closeness reads instantly as intimacy, two young people wrapped up in each other on a frozen block of the Village.

And yet the casualness that makes the picture so disarming was almost an accident. There was no studio, no styling, no plan beyond a photographer telling them to walk up and down the street on a freezing afternoon. What that unplanned walk turned into is the story of the image itself.
