Peter Grant visited Pakistan in 1995 and photographed myriads of decorated vehicles, a gallery of which photos can be found here: http://www.pakistanphotos.co.uk/pakphotos/index.html   I am reproducing his history of these decorative arts here:  This extraordinary tradition has it’s roots in the days of the Raj when craftsmen made glorious horse-drawn carriages for the gentry. In the 1920’s the Kohistan bus company asked the local Michelangelo, Ustad Elahi Buksh, a master craftsmen to decorate their buses to attract passengers. Buksh employed a community of artists from the Punjab town of Chiniot, who’s ancestors had worked on many great palaces and temples dating back to the Mogul Empire. It was not long before truck owners followed suit with their own designs. Through the years the materials used have developed from wood and paint to metal, tinsel, plastic and reflective tape. Within the last few years trucks and buses have been further embellished with full lighting systems. A new undecorated bus costs around £3000 after which owners can expect to pay a further £5000 for a complete decoration which can take up to three months. The cost of decorating a truck is around £3000 on top of the £1500 paid for a new vehicle. Artists are paid between £1.50 and £3 per day. [These costs go back to 1995. I have no idea what they are today. JK]
