A 98-year-old drawing of a Thanksgiving turkey was preserved on a blackboard that had been covered over in a school renovation in Oklahoma City.
For some reason, teachers decided not to erase the blackboards at Emerson High School in Oklahoma City, Okla., before a long-ago upgrade of the facility.
So when workers were removing the green chalkboards from classrooms during a recent renovation, lesson plans, drawings and assignments from 1917 were still on the blackboards that were uncovered.
KFOR-TV reports that educators were amazed when they saw the old lessons underneath their walls, they could not believe their eyes.
“I was like, ‘Oh my God,’ and then I got goosebumps and then I had tears in my eyes,” Principal Sherry Kishore said.
