Last week, a billboard advertisement for a parking lot in Chelsea was mysteriously altered with bucket paint and it appears to be the work of public space-altering artist Poster Boy. A video was uploaded to his Flickr on Thursday showing the modification. The advert originally read: “WTF is alternate side of the street parking anyway?” But with the help of a paint roller on a very long extension pole and parking attendants too busy doing their jobs to notice, it was changed to something a bit more topical.
