It's not beyond the realm of possibility for a traitor to look half-way presentable on a postage stamp.
E.g, Kim Philby, eight years Helen's senior.
Kim Philby was a real POS. May he rot in Hades. I know we joke a little about Thomas getting on a stamp, but if I am not mistaken, Hitler was man of the year, on a magazine cover at one time, so stranger things have happened.
