Authenticated by the last member of the Group of Seven

Every piece offered here comes from the last surviving inventory of original Sampson-Matthews oil silkscreens — works produced between 1942 and 1963 under the supervision of A.J. Casson, Vice President and Creative Director of Sampson-Matthews Limited and a member of the Group of Seven.

Unknown to anyone until 1990, this inventory survived in the estate of founding partner Charles Matthews. When the works were located, A.J. Casson — then in his 90s — personally inspected and authenticated each one, signing “Supervised by A.J. Casson” on the face of the piece. Works he had himself translated from painting to silkscreen, including images by Emily Carr, Tom Thomson, and Casson himself, he signed simply “A.J. Casson.”

These are not copies or mechanical reproductions. They are original, hand-pulled silkscreen artworks. Each piece is sold with a Certificate of Authenticity and is one of a kind — once a piece sells, it is gone, though it remains on this site as a record of the collection.
