My Great-Grandfather Andrew Clifford Jack (1875-1958), the youngest child of Andrew Jack and Rebecca DeWitt, was a surgeon dentist in Montreal and a teacher of dental anatomy at McGill University's dental school. Family lore recounts how he used to pull teeth for free on the community dock at his cottage in the Laurentians. One of the items in that big box of family documents was an envelope containing business cards and personal calling cards; they all appear to have been collected by Dr. Jack, and some can be dated to the 1920s. Most are from Montreal, but there are also some from other places. There are cards from both his personal life and his professional sphere. These business cards are solidly in the realm of, "kind of neat to look at, but not all that useful to me genealogically-speaking." Maybe they will be of interest to others, so I'm posting them here. I am tagging them all as "business cards", even though some are more accurately "calling cards."
