Mural-like painting advertisements on exterior walls are one of the cheapest and most effective methods of advertising in rural India, especially in areas which do not have billboards. Usually, wall painting comprises of paintings in the interiors of cities, villages, next to railway stations, bus stops, in and around shops and the market areas.

Wall painting is also used for “guerilla marketing tactics” where companies, which have low or no market share of their product, use wall painting to generate brand awareness in a particular area. Thus, wall painting serves as the cheapest and most effective medium to reach villages and mass audience.
