Ever look at a graffiti wall and wonder what would happen if you scraped off a bit of paint? Well, Imgur user Paul De Graaf saved you the trouble by chipping away at a wall of graffiti in the Netherlands. This is what he found.
Over 30 years of paint caused an incredibly colorful stratification that is almost like reading the rings on a tree trunk. The hardened layers of paint form a vivid timeline all the way back to the 1980s, when this space in the town of Nijmegen became a center of art and music. De Graaf has even cleverly created a visual look at history using the paint itself. In this case, walls really do talk.
