he Cold War heated up at Expo '67 in Montreal after world's fair officials placed the Soviet Union and the United States pavilions across from each other. The Americans stocked their 20-story geodesic dome with Elvis Presley's guitar, Andy Warhol's paintings, and Raggedy Ann dolls, while the Soviets furnished their pavilion with dozens of furs, 6 tons of caviar, and 13,000 bottles of vodka. The Soviet Union's 35-foot-high stylized hammer and sickle served as a stark reminder of tensions between the superpowers that lasted until the "evil empire" crumbled into history 24 years later.
