While walking around Florence, have you noticed something different about some of the street signs? Clet Abraham is a French artist who stealthily alters traffic signs with graphic stickers that transform a DEAD END sign into a crucifix or a ONE WAY arrow into Pinocchio’s nose. In the artist’s jumbled studio in San Niccolò, you can learn a bit about his process and purchase a sign of your own. If the original works are too pricey, there are also vinyl stickers and T-shirts bearing his whimsical designs.
