nyhistory: Hidden, or disappearing, fore-edge painting is a technique that dates back to the mid 17th century, when London bookbinders began decorating not the flat edge of a text block, but rather the gently fanned edge. Doing so caused the image to appear and vanish depending on how the pages were held. In some cases, as with the views of Boston and Philadelphia above, two different scenes were painted on either side of the fore-edge, so that only the gilt edge is visible until the pages are fanned in one direction or the other.
