History enthusiasts in a small Minnesota community outside of Minneapolis gathered with press to open the 1920s-era box buried under an unassuming corner stone.

The tattered white box was recovered as construction workers tore down the front pillars and doors of the former Owatonna High School in Minnesota, which was built in 1920.

As construction crews tore down an old high school building, a school employee alerted them to an engraved cornerstone that read "AD 1920." He was just in the nick of time, and folks are glad to take an unexpected peek back at their local history.
