George Alexander Drew (1894-1973) was Canadian conservative politician who served as Ontario premier from 1943 to 1948, as federal opposition leader from 1948 to 1956, and as Canadian High Commissioner to the UK from 1957 to 1964. The photos usually feature George and his wife Fiorenza and children Sandra and Edward. The cards likely went out to a large number of people and these don't state to whom they were addressed.
