The canine-- humankind’s best friend, celebrated in literature, art, cinema, cartoons, and this year--at the San Francisco Public Library! A Dog’s Life (With a Special Appearance by Cats) is a comic take on dogs and their sometime sidekicks, cats. Drawn from the Schmulowitz Collection of Wit & Humor, the annual wit & humor exhibition features the work of New Yorker and Punch magazine artists, as well as the old New York Life magazine; classic and beloved characters from newspapers and comic books; and a little look-see at doggish anecdotes and illustrations from around the world. Presented by the Book Arts & Special Collections Center, the exhibition opens April 1, and continues through May 31, in the Skylight Gallery, Sixth Floor, Main Library.
