Although he had no formal training, his highly recognisable style has won him considerable representation in many important Australian collections. His works are often explicitly social, referencing human isolation, and finding their depth in haunting depictions of lonely and outcast figures. The only Sydney-based member of the Antipodean artists’ group in the 1950s and 60s, Dickerson is associated with prominent Australian artists such as Blackman, Boyd and Perceval. He is an unquestionable master of colour and drama, and a considerable body of charcoal and pastel drawings complements his paintings."
