Gene A. MacDonald?
I showed R my clever discovery, and she remarked that John A. had a remarkable resemblance to comedic actor Gene Wilder. I was astounded, and began searching the web for a photo to prove this. Apparently her friend thought it was Gene Wilder on our $10 bill. Heh. I never thought he was that great an actor.
Seems to me, if anyone goes on our $10 bill, it should be Anne Murray, or possibly William Shatner.
