Unscathed century old chalkboards were discovered in an old school in Oklahoma recently. Conservative audiences have picked it up, calling it a reminder of how far we have slid culturally in the past century. The old adage of taking God out of the classrooms come to mind. I was impressed by the lesson plans, and I fear our public schools were definitely doing a better job teaching students back then. The art was also very nice and refreshing in a sense, drawing must have been more common then. A curator said the boards cannot be moved, surprised some sort of epoxy mist could not be applied. Curious how the art museums keep their priceless chalk and charcoal pieces.
