Blackboard Jack (Painting on blackboard at school)

It is art activity/performance by students of Musashino Art University since 2011. 

They draw fine arts with chalk on blackboards of classrooms in elementary, junior high and high schools before school time. 

It would be big surprise for children and they enjoy communication each other through beautiful paintings. 

It is a rule to erase them all before the class after children appreciated the paintings.
