Dickerson was a self-taught artist who refused to go to art school. His art has been described as angular and high contrast
chiaroscuro and executed in a range of materials including paint, pastels, charcoals and other graphic media. The inspiration for his art came from everyday life and he drew on the themes of loneliness, vulnerability and isolation. In November 1955, art patron
John Reed published an article in Ern Malley's Journal (Vol 2) which described Dickerson's work as containing "a new sense of beauty, a new truth". But his break as a professional artist came in 1954 when the
National Gallery of Victoria purchased his work
Man Asleep On The Steps. In 1959 he joined Charles Blackman, David Boyd, John Brack, Bernard Smith,
Arthur Boyd and
Clifton Pugh to form the Antipodeans—a group of figurative artists making a statement opposing abstractionism in their day. According to the former deputy director of the National Gallery of Victoria, Frances Lindsay, members of this group continue to be 'productive and innovative after many decades of practice. ==Early life==
