7. He Made Three Copies of Each Painting
Every painting featured on The Joy of Painting exists as three separate copies. The first is a simple reference copy that Ross worked from while doing live art for the aired episode. The second copy is the actual painting created on the show itself. Finally, a far more detailed version that was intended to be used by Bob Ross Method instructors in their classes and teaching materials is the third copy. With 403 episodes, this means that Bob Ross created over 1,200 paintings for The Joy of Painting alone.
