Tart cards coffeetable book and online galleries
Coffeetable book of the year: Tart Cards: London’s Illicit Advertising Art. "Tart cards are the means by which providers of sexual services advertise, and they have become as ubiquitous a symbol of that city as the red telephone boxes in which they are found. Since the early 1980s these advertising cards, posted in public phone booths around London, have evolved with technology into a sophisticated graphic and sociological form." The form has apparently spread to Japan.
