US men's adventure magazines of the 1940s, 1950s, and 1960s had titles like "True Man", "Men Today", "Man's Adventure", "New Man", and so on, and are collectively known as "Sweats" because of the sweaty blue collar heroes their covers often feature.
The covers typically feature some attractive women popping out of their tops, as Nazi sadists get ready to brand them or flog them or bury them alive.
Said attractive women often have a "here we go again" facial expression, and no wonder - Nazis torturing attractive women seems to be a staple of these titles.
Sometimes, though, the magazines deal with rugged American men unfortunate enough to fall into the hands of Nazi women.
These magazines were first published for the WWII veteran market so they pretty much invented our iconography of Nazi bondage sadism.
