In 1946, A. J. Casson was still working full time at Sampson-Matthews. His sketch trips consisted of weekend road trips or vacation time.
The 1940’s represent a transitional period of Casson’s career from his Group of Seven influenced work to his own creations and experiments. His years of graphic design working on silkscreen images for Sampson-Matthews affected his painting technique. Shapes and compositions were simplified and his colours became slightly muted in comparison to his early work.
Mr. Casson would continue working at Sampson-Matthews until 1957 when he retired to paint full time. He began working exclusively with Roberts Gallery in 1955 and held his first solo exhibition there in 1959. He went on to have 11 solo exhibitions at Roberts.
