Abstract
Abstract One section (1) of a rectangular frame is releasably secured to the remainder of the frame, in which a backing board (7) is located. When the device is fixed to a site location, the said one section (1) remains removable without damaging the site location, so as to allow a sheet (8) of artwork to be inserted into the frame in a direction parallel to the backing board (7). The artwork sheet (8) projects at least partly beyond the edge of the backing board (7) adjacent the removable section (1) so as to be grippable to facilitate removal of the artwork sheet (8).
