NEW YORK (AdAge.com) -- An exhibit of print advertising is as filled with stunning creativity as it is with pure horror. Santa Claus hawks cigarettes. Doctors recommend cigarettes as cures for various ailments. Dentists urge their patients to smoke. Babies endorse the cigarettes their "daddies" smoke. The display -- covering ad agency output from the 1920s to the 1950s -- fills the walls at the Science, Industry and Business branch of the New York Public Library.
