Next time youre perusing old books in your personal library, you might want to see if one or more of them contains an amazing technique called a fore-edge painting an illustration that is hidden on the edge of the pages of the book. Reportedly, the technique dates back to the 1650s. To see the painting, bend together the pages of the book to where you can just see a small piece of each page.
The time it must have taken to put into each work is staggering
Some books even have double fore-edge paintings, where a different image can be seen by flipping the book over and fanning the pages in the opposite direction.
These works of art are now being sold for hundreds (and sometimes thousands) of dollars.
Heres one of the best examples of the same technique. Amazing!
