Personally I think it's fine apart from some questionable anotomical knowledge (the head looks small and the forearms are curved). but I doubt most people will even notice, never mind care.
As for reminding people of stuff I think it'll more likely to be associated with Superman or such like, I don't think there are many in our potential market 67 years old.
I don't think there's anything Nazi abut it, it looks like a generic super hero to me. If it had a swastika* then there'd be something to complain about.
*The swastika is only a symbol the Nazis picked up, it's been around for thousands of years and is thought to have originally come from a passing comet. Read "Comet" by Carl Sagen for more details.
