I call the interplay between painted text on brickface and graffiti/streetart an “urban ediglyph.” The etymology of this word comes from the words ediface– an imposing building (in this case a building wall) and petroglyph – ancient rock engravings left behind by earlier indigenous cultures. Often the earlier fading ad is somewhat indecipherable but takes on a newer meaning with the addition of the streetart or urban tagging. Here are two from Seattle that I thought merited a blog posting.
