Which U.S. city buried a 1957 Plymouth Belvedere as part of a time capsule for its state's centennial?

In 2007, the city of Tulsa, Oklahoma unearthed a 1957 Plymouth Belvedere as part of its state's Centennial celebration. This was part of "Tulsarama", which was an event in June of 1957 to commemorate Oklahoma's 50 years of statehood. "Miss Belvedere" was intended to go to the person, or descendent if they were not alive, who was closest to guessing the actual population of Tulsa in 2007. Other items were put in the car as part of this time capsule. These items included a purse, motor oil, gas container and a rain hat as well as a savings account document for the winner of correctly guessing Tulsa's future population. The car was also part of this prize.

On June 1957, the Belvedere was buried underneath the Tulsa court house as part of a time capsule meant to be dug up 50 years later. The car was a brand new, two-toned white and gold sports coupe.

The concrete vault was not air-tight and there was significant water damage to the vehicle, which made it inoperable at the time of the excavation. It was suspected that a construction event which damaged a water main in 1973 might have attributed to the significant amount of water in the vault. An effort to restore the car was made and the 1957 Plymouth now resides in Historic Auto Attractions Museum in Roscoe, Illinois as of June 2017.
