At the Peterson Automotive Museum in Los Angeles, California visitors can see a bright yellow car with a unique design, built with promises that seemed too good to be true. At the Bakken Museum in Minneapolis, Minnesota, a glass and wooden musical instrument tells the tale of miraculous medical cures that came under the scrutiny of one of America's most famous statesmen. And at the International Spy Museum in Washington, DC, a small piece of paper tells an epic story of espionage, secrecy, and a very unlikely spy during a trying conflict.
