These artists use a medieval illustrative magic to make images appear in books
I made this!
These books are placed around a library for the public to find and activate. The hidden images are drawn using an ancient technique. There are many books around the world with such hidden images, try a book you have or found to see if it has such an illustration hidden in the fore-edge. These works are available for libraries around the world.
