There will be a new exhibit in Muncie, Indiana coming on Bob's birthday in 2020. The link to it is here.
I hope nothing happens to prevent this event from happening because it will be located in the same house and studio that The Joy of Painting was filmed from 1984 to 1988. There will be some of the actual Bob Ross paintings on display when it opens, which will be very cool to see. The Joy of painting is also being enshrined in the Indian Broadcasters Hall of Fame in 2020.
