Researchers recently discovered an unassuming bookmark in a 19th century French novel that featured three sketches by Vincent Van Gogh. In 1883,  the artist gave a friend the book and more than a century later, researchers discovered that the novel contained a handmade bookmark, with a set of early drawings  by Van Gogh. The three sketches are on a single strip of paper. Each shows a single figure—possibly farmers inspired by characters in the book.

The drawings are on display in "Here to Stay," an exhibition at the Van Gogh Museum in Amsterdam that features artworks and other items that have entered the museum's collection over the past decade.
