"As the publication date drew near for Slaughterhouse-Five, on which Vonnegut had worked, fitfully, for 20 years, he brooded over his author photo. He was clean-cut, clean-shaven, a bit paunchy—in 1969, an unlikely candidate for cultural eminence. He decided “to cultivate the style of an author who was in.” “To meet the expectations of his audience was key,” Mr. Shields writes. “He lost weight, allowed his close-cropped hair to become curly and tousled, and grew a moustache. … He looked like an avant-garde artist and social critic now, not rumpled Dad-in-a-cardigan.” His upper lip would never reappear. Slaughterhouse-Five became a number-one New York Times best-seller, and its tousled (not rumpled) author became an icon of the counterculture."
