"Writers have noted that there are now distinctions to be drawn between how lowbrow manifests itself in different regions and places. Some see a distinct U.S. "west coast" lowbrow style, which is more heavily influenced by underground comix and hot rod car-culture than elsewhere. As the lowbrow style has spread around the world, it has been intermingled with the tendencies in the visual arts of those places in which it has established itself. As lowbrow develops there may be a branching - as there was with previous art movements - into different strands and even whole new art movements."
