“We don’t make mistakes, we have happy accidents,” is perhaps Bob Ross’s most famous mantra, one he repeated in various formulations throughout the 11-year run of The Joy of Painting, his instructional TV program on PBS. More than two decades after his death, the popularity of the iconic painter, famous for his round, permed hair and quirky, endearing remarks, still hasn’t waned. In fact, it is gaining renewed interest.

Happy Accidents will be the title of a new exhibition of the iconic painter’s works, due to open on September 10 at the Franklin Park Arts Center in Purcellville, Virginia. The exhibition will feature 24 original Ross paintings created on The Joy of Painting, the largest collection of Ross paintings to ever be displayed at a gallery. It will also be the first Bob Ross exhibition on the East Coast.
