 | | Quack, Quack, Quack, on view at the Grolier Club from September 18th to November 23rd 2002, showcases the often flamboyant sellers of nostrums and patent medicines over the course of four centuries, through visual, often entertaining, material. |
 | | These range from the ways of itinerant quacks, their use of various extravagant marketing techniques, the frequent bitter rivalry between sellers of panaceas, each with his or her own theory supported by dubious claims of efficacy; to quacks in the arts and, finally, to the first governmental restrictions on the more flagrant abuses. |
 | | Altogether, Quack, Quack, Quack: The Sellers of Nostrums in Prints, Posters, Ephemera and Books comprises 185 items, all drawn from the collection of William H. Helfand, who has curated the exhibition. |
