A 1957 model was buried brand new beneath the Tulsa Courthouse in Oklahoma and was unveiled in 2007 exactly 50 years to the date it was buried. However, it was heavily rusted from water that seeped into the vault and all that was intact were items held in a sealed cylindrical capsule.
Mark: (On the opening of the capsule). No, Debi...it is just a bunch of prom dress catalogs and baseball cards. And everything is all wet. Looks like they Belvedered this one, too.
