Aboriginal Dot Painting
Aboriginal dot painting originated in the Papunya settlement in Northern Territory, northwest of Alice Springs, in 1971.  In addition to canvases which are sold in art galleries around Australia, one sees a lot of this kind of design on construction hoardings and bunting and in a commercial context.  One gallery director I spoke with described the latter works somewhat dismissively as "graphic design."
