All-over painting
All-over painting refers to the non-differential treatment of the surface of a work of two-dimensional art, for instance a painting. This concept is most popularly thought of as emerging in relation to the so-called "drip" paintings of Jackson Pollock and the "automatic writing" or "abstract calligraphy" of Mark Tobey in the 1950s, though the applicability of the term all-over painting would be wider than that.
