The art of vanishing fore-edge painting—hiding delicate images on the front edges of gilded books—dates back to about 1660. Today, British artist Martin Frost is the last remaining commercial fore-edge painter in the world. He works primarily on antique books, crafting scenes from nature, domestic life, mythology, and Harry Potter. Great Big Story recently caught up with him in his studio to learn more about his disappearing art. Learn more in the video below.
