This ad gets straight to the point: if you don’t buy life insurance, you will wind up old, helpless, forlorn, penniless and unwanted. You will suffer and, presumably, you will die.
This ad is actually an early example of feminist thinking: for a change, a young woman is being asked to provide for her own future, rather than wistfully hope that Mr. Right will do it for her. This is quite forward thinking for the time, given that women in Canada had only had the right to vote for ten years and the right to run for election for seven.
