See ^^ video. Bob Ross would paint an entire landscape in 30 minutes. He learned some of his techniques from another older gentleman named Wilhelm (Bill) Alexander who I watched as a young teen before I ever heard of Bob Ross. Bill would do the same Bob did and complete a whole landscape in 30 minutes.Who is Bob Ross?
