Upon first glance, this may just look like a regular old map. But the image, posted to Imgur, has been causing much hilarity on the internet, as viewers realise the map contains the outline of a woman's body.
The map was posted by user Shinygreencloud with the explanation: "This map has hung in my firehouse for years. I just looked at it for the first time."
Upon closer inspection, the firefighter realised the hills, valleys and mountains in fact depict the shape of a woman's body. And names on the map appear to play to the cheeky cartography with landmarks such as "Naval Reserve" on the figure's stomach.
The image has been viewed over 2.5 million times since being posted on the photo sharing site and has also been posted to Reddit, where it has sparked much amusement.
One eagle-eyed viewer spotted a caption on the map that read: "Aerial photographs taken in 1982. Field checked last night."
Another viewer, a geologist who goes by the name Sailthetethys, said: "This map makes my whole life. Oh god, the scale is in cup sizes."
The firefighter who posted it promised to find out where their chief had got it from as several fellow Imgur users wanted to gift a copy to their fathers.
Aviator 68 replied: "Please don't fail. Would be a great gift for my cartographer father."
Meoka2368 added: "My dad was a pilot and is currently a lighthouse keeper. He too would love this."
