“It’s a type of safe that was designed to make it even harder to break into,” she said. 

Graff’s expertise in nineteenth- and twentieth-century archaeology in the Chicagoland area is being utilized to unravel what lies within this cannonball safe. 

All we know is that a man sold the piece of land in the 1920s for millions of dollars and a hotel was supposed to be built on the property, but never was. Graff will continue to be part of the process of analyzing the safe and its contents in the coming weeks.
