I visited the Mütter Museum (a great collection of medical and related memorabilia and information in Philadelphia), which had the following sign on one exhibit about shrunken heads: “Westerners traveling to the territory in the late 19th century … were fascinated with the heads and offered the tribe money and guns in exchange. ... This led to an increase in warfare … both to get more heads to sell and because of the prevalence of guns. It also led to the creation of counterfeit heads … made from real human heads but not prepared by the tribe, and others [that] were made from monkey, goat, or other animal skin.” Nice to see how, even for a bizarre object, a large increase in demand elicits a supply response of both genuine and fake products.
I welcome other equally weird examples of induced supply responses with both genuine and fake products.
