I like the way street artists now glue paper on Paris walls instead of painting them with spray paint. It allows passers by to discover new artists without damaging the walls, nor costing money to tax payers (for the city has to clean these walls eventually, no matter what). I really love this one, shame that it's not signed. UPDATE: thanks to the help of a few good visitors ;-) I know now that this image was used for the cover of a record by FKA Twigs (London).
