There is an interesting 16- by 20-foot mural of Nelson Mandela on the side of this home. The addresses I used are approximate. It is near 16th and Fitzwater in the Graduate Hospital neighborhood. The artist is Londoner Ben Slow. He uses a streaky style called drip technique. (I see some boards on the Web with opinions that the artist was simply sloppy, which was not the case.) This information is from an article in today's Philadelphia Inquirer by Michael Matza, at p. B1.
