Our Net friend Kevin recently ran a surprising shot of Prince Namor the Sub-Mariner wearing a costume from the early 1940's at BeaucoupKevin(dot)com. BlogMachineGo. This, of course, was a revelation that we ourselves had run across some time back. To be precise, here: http://booksteveslibrary.blogspot.com/search?q=golden+age+sub.
Now, today, we reveal the Prince nattily attired for a weekend in the country with his police officer girlfriend, Betty Dean. Not really a "secret" identity but he's definitely attempting to pass. In fact, he wears the clothes through much of this story (from HUMAN TORCH # 9) which is a landlocked haunted house story!
