Atoms of Death... the answer

"Agent J reports: Three dots after 'Codes', mustache moves from man on right to man on left, The Shadow's hat brim, gold band on cane. That's all I can find. I believe this is supposed to be The Shadow and his 2 disguises - Lamont Cranston on the left and Henry Arnaud on the right"

Pretty good, Agent J.  Just The Shadow's crimson collar is all you missed.  Hope 2020 been good to you so far and thanks for playing.
