A lovely book “by Massachusetts based artist and teacher Frederik Whitney (1858-1949) on the lost art of blackboard drawing”.

“Ability to draw easily and well on the blackboard is a power which every teacher of children covets. Such drawing is a language which never fails to hold attention and awaken delighted interest”.
