The Voynich Manuscript may have a challenger for the most mysterious document: at Imgur.com, user TramStopDan2 posted this amazing gallery of images (update: and also a second gallery) showing the fantastical ufological/Fortean/religious texts and illustrations found within a mysterious box:
So a friend of mine found this box by the trash, it is full of wonderful, crazy illustrations. Clearly something happened to this guy that was very memorable. It measures roughly 29" by 38" and almost all the drawings are very large.
Drawings like this, combining both religious iconography with technical drawing:
The cache of documents - which seem to date from the 1930s through to the 1990s - contains texts on UFO research, maps of the world, religious-themed illustration and much more.
What do you think? Viral marketing? Genuine ramblings of a fellow explorer of the strange? Or perhaps, the answer to everything...
