During renovations, a high school in Oklahoma City recently discovered a series of old chalkboards under their existing ones, covered in writing that had remained untouched since 1917. The preserved boards include lessons on music, math, and even the history of the Pilgrims. It’s a fascinating little time capsule from an earlier era, particularly since it was one that was always meant to be wiped away.
