Frames styles come and go every decade or so.  We have seen so many over the years, from the ornate to the glossy aluminium, from the gaudy, ornate  gold to the plain white, and many more. Yet there is something incredibly functionally simple and elegant about clip frames. The design has stayed remarkably consistent over the years, perhaps because it is so uncomplicated and basic.  It has no visible wood or metal edge or border and consists of a backing board and a pane of glass with the artwork sandwiched in between, all held together by clips.
