Anyone who knows which issue was the last one where we could see him with his original mustache? Even if it's something most people associate with Hitler, a toothbrush mustache is also associated with people like Chaplin and Oliver Hardy. And J. Jonah Jameson. I was so used to seeing it on him that Hitler never crossed my mind. But after the movies became big hits, new readers came to the comics and social media became more common, I guess Marvel deiced it was time for a little upgrade.
