Just not with Superman on the cover... I have many of those other Hitler parody covers but this one is very appealing to me for 2 reasons, 1st I don't think there are too many covers with both Superman and Hitler on the cover (correct me if I am wrong) and second I find the Fred Ray art on this cover particularly appealing.
You‘re probably right about being possibly the only one cover with Superman and the dictators, but I was just saying that I find more suggestive other Action covers, where Superman for example helps soldiers or protects them from certain death. They have a deeper meaning, although of course this cover is probably the only one with Hitler.
They are just too pricey for me…
In addition to Superman #17, he also takes on Hitler, Hirohito, and Mussolini on the cover of World's Finest #9. Otherwise, DC didn't feature very many Hitler covers. Others are All Star #24, Boy Commandos #2, More Fun #75, and Sensation #13.
