If you close your eyes and think, you can probably conjure Guy’s best-known images. He was prolific in the 1960s and early 1970s. He shot album covers for the Doors, Simon and Garfunkel, the Rolling Stones. Shirtless Jim Morrison, that was Guy. Michelle Phillips stretched out in a bathtub across John Phillips, Denny Doherty, and Mama Cass, that too. You can remember how delicate those pictures are. Just little, perfect, telling instants.
