This may not be completely relevant to the discussion on autographed notes, but I thought there might be some interest in it. Twenty-five or thirty years ago I was invited to be present when a former member of the BoC curator's staff interviewed an elderly lady who had been employed by the Department of Finance to sign Princess Patricia $1 Dominion notes. At the end of the visit she consented to sign some then-current $1 bills for us, just as she had signed the 1917 Princess Pat's - see scan. (I have been watching for a Princess Pat $1 with her signature since, but no luck.)
