Martin Frost is a painter who creates artwork that people can’t see if they are not specifically looking for it. Frost is a fore-edge painter who does his art along the edges of books, but it’s visible only when you fan the pages in a certain way.
As Frost says, “It is a discrete painting. It is only there when you know how to unlock it.”
This art form dates back the to the 17th century, and Frost has been practicing it for 40 years. As he says, he’s the last commercial fore-edge painter on the planet. Check out his beautiful work in the video below.
