Hard to believe kids drew all these incredible pictures and there's not a boob to be seen.

Contractors at Emerson High School in Oklahoma City were removing chalkboards to replace with whiteboards only to find another layer of chalkboards underneath`that had been untouched since 1917. They're very cool and creepy as hell, because the people who drew them are all dead now. But they sure knew how to draw a turkey!
