Sometimes the greatest artworks are hidden in plain sight. Case in point: the University of Iowa recently discovered a four-volume set of scientific books from 1837 contains hidden paintings on the edges of the pages, which only show up when you fan them part-way open. These "Fore-Edge Paintings" are everywhere, and they're beautiful.
As Flavorwire explains, Fore-Edge Paintings go back to the 16th century, "when Italian artist Cesare Vecellio (cousin of Renaissance painter Titian) started using his books as a canvas in order to beautify them." A bunch of them were posted by the University of Iowa and the Boston Public Library, and check out some of our favorites below.
