Nick Fury and Spy Smasher

I remember thinking that Spy Smasher was cool when I was introduced to him in the pages of a JLA/JSA crossover that featured the "Earth-S" heroes.  At the time I figured that he was just another c-list Fawcett character but it turns out that he had quite a presence back in his day with plenty of solo adventures and even a live action movie serial adaptation.  They got the costume perfectly right in that serial, too - which is more than Batman or Captain America could say.
