Pakistani trucks are also used as means of displaying the owner or the Painter’s Poetic taste. It also serves as a calligraphic board as well as a notice board for public messages.

Note the two photos below. In the photo to the left the truck owner is declaring himself as hopelessly romantic (ye dil hai aashiqaana) and in the photo to the right he is requesting his beloved to accompany him to his hometown, which is by the way, Khuzdar Balochistan. (aao sanam Khuzdar chaleN)

History of Vehicle Painting in Pakistan:

Atleast one website (here) gives following history of bus/truck painting in Pakistan and quotes it to one Peter Grant.

Pakistan Truck ArtThe extraordinary tradition of decorating trucks has its roots in the days of the raj when craftsmen made glorious horse drawn carriages for the gentry. In the 1920s the Kohistan Bus Company asked the master craftsman Ustad Elahi Bakhsh to decorate their buses to attract passengers. Bukhsh employed a company of artists from the Punjab town of Chiniot, who’s ancestors had worked on many great palaces and temples dating back to the Mughal Empire.
It was not long before the truck owners followed suit with their own design. 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
