The walls of Roger Smith's office are covered with pictures of Ann-Margret. Here she is as a sex kitten, on the cover of Life. There's a cover from Entertainment World, a forgotten show business magazine. All in a row are three recent covers of People. And here are an oil painting of Ann-Margret, and a lot of cartoonist's caricatures, and some framed ads and telegrams and the usual backstage memorabilia. In one corner, almost hidden behind a file cabinet, is Roger Smith's only souvenir of his own career: A framed ad for his stage appearance as a folk singer at the "hungry i" nightclub in San Francisco, in 1964.
