OKLAHOMA CITY - Officials with the Oklahoma City Public Schools District announced a historic discovery at a high school that's undergoing renovations.

Officials said this week, while removing the “whiteboards” currently in classrooms at Emerson High School, contractors discovered several chalkboards with writings and student drawings from 1917.

The work assignments of teachers from nearly 100 years ago are still intact, and the images can be found in three classrooms.

The Oklahoma City Public Schools District is now working with the MAPS for Kids Trust in identifying a way to preserve the “chalk” work of the teachers that has been captured in time.
