Similar to the fable gypsy bands of old Europe, medicine shows were traveling horse and buggy teams which peddled miracle medications and other products between various entertainment acts. Their precise origins unknown, medicine shows were most common in the United States in the 19th century (though they continued up to World War II). The product most commonly associated with medicine shows is an elixir (also known as snake oil) which was touted to cure diseases, smooth facial wrinkles, remove stains in clothing, prolong life, or cure any number of common ailments. Entertainment often included a freak show, a flea circus, musical acts, magic tricks, jokes, and storytelling.
