Well, I missed the exact anniversary of starting this thread, but better late than never.
This may not be the best Hitler cover, but it has been the most difficult to find (for me).
I've had pretty much all the golden age Harvey superhero books over the years, but I have never even actually seen this one in person.
That's why I bought it when I had the chance.
Heritage has sold two raw copies (one good, one fair/good) in its history. The CGC census lists 5 universal copies. One 9.6 (the Mile High, sold by CC in 2012 for $7,000), 2 at 5.0, 1 at 4.5, 1 at 1.5.
So this original owner copy might be the second highest if I sent it in.
Just something about the Kirby Captain Freedom (and Hitler) cover. Always wanted one.
