The February 17 1949 edition of the Toronto Daily Star contained two interesting ads for entertainers. One was for all the way out in Burlington, and featured that weird disembodied head look that sometimes appeared in ads at that time:
The other featured more conventional headshots:
Both of the entertainers featured here were (arguably) on the downside of their careers when they appeared live in the GTA. Sully Mason (1906-1970) was one of the singers in Kay Kyser‘s band during the Second World War, and Valaida Snow (1904-1956) was a multi-instrumentalist (focusing on trumpet), singer, and dancer who toured the world in the late 1920s and 1930s. Tragically, both of them died relatively young with the same cause of death: a cerebral hemorrhage.
