On June 15th, 1957 the residents of Tulsa, Oklahoma buried a 1957 Plymouth Belvedere beneath a downtown sidewalk in front of the Tulsa County Courthouse. At the time Tulsa has more cars per capita than any U.S. city besides Los Angeles and a fierce rivalry with Oklahoma city. The time capsule stunt was meant as a way to celebrate the city's love of the automobile and one-up Oklahoma City.
The car was filled with all sorts of 1957 mementos, including a case of Schlitz beer, 10 gallons of gasoline, 5 quarts of oil, the contents of a lady's purse, as well as photos and maps of the Tulsa area. No one knows what condition the Plymouth is in, but townsfolk from the era say city officials took every precaution to ensure the car would still be pristine when it was exhumed. That date will come next year during Tulsa's centennial on June 15th, 2007, fifty years to the day after the car was buried.
