A man has posted a map online that features a naked woman within it - and admitted he'd only just noticed this fact after years of it hanging on the wall.
We first spotted the mage on the Metro, but Reddit user shinygreencloud originally shared the picture and wrote: "This map has hung in my firehouse for years. I just looked at it for the first time."

Online users have been laughing at the map's names, including the strategically-placed Beaver Valley, Naval Reserve, Back Arc Basin and Windy Ridge.
A number of people also found the map's title amusing as it's named Twin Buttes 7.5 minutes series (Pornographic).
One user wrote: "This map makes my whole life. Oh god the scale is in cup sizes. The adjacent quad is Miss September. I need this."
Another laughed: "I literally live in the Beaver Valley in PA. None of this looks familiar."
