These two first day covers were autographed by the stamps' artist Alfred Joseph Casson (1898 - 1992). He was a member of the Canadian impressionist painters "Group of Seven". He was the eighth member, as he was asked to join in 1926, after the founding of the group in 1920. For much of his professional life he was also a commercial artist who designed posters, magazine covers and other images. As far as I can tell, these are the only two stamp designs he created.
