Tart cards are cards advertising the services of prostitutes. They are found in many countries, usually in capital cities or red-light districts. The cards originated in the 1960s as handwritten postcards outside prostitutes' flats in places such as Soho, London, where they often contained euphemistic references to sex. By the late 1980s they had become black-and-white photocopied cards containing printed text and telephone numbers. In later years they appeared in colour and included photographs and mobile telephone numbers or websites. Over time they have become regarded as items of ‘accidental art’ and developed a cult following. They have influenced the work of mainstream artists, inspiring collections, research, exhibitions and books.
Tart cards by country
- United Kingdom: in London they are placed in phone booths by professional "carders", who tour the phone booths, replacing cards which have been removed by the telephone companies' cleaners. Carders often remove cards placed by rival carders. In the UK, placing them in phone booths has been illegal since the passing of the Criminal Justice and Police Act 2001, although the practice still continues. In Northwest England the cards are known as slag tags.
