A 100-year old blackboard which has been hidden in the walls of a classroom in the city of Oklahama. The drawings and writings on the blackboard have been hidden and preserved
since 1917. The discovery of these hidden drawings have been made, since the building is being renovated which is currently the Oklahama High School. The Teachers in the High School
are being surprised with the way the classes have been held a century earlier with colorful pictures drawn on the blackboard for the clear understanding of the lesson.
Do you really miss it? The classes told with chalk on the blackboard, and the life as a kid with no mobile phones, no facebook, no internet where you feel the real happiness..
