A cavity (25) is formed in the floor of a building for receiving the floor type advertising apparatus. A magnetic layer (31) is located and secured in the lower portion of the cavity (29). A metal layer (37) having an opening (39) formed therethrough is att- ached to the lower side of a transparent layer (41) and both the transparent layer (41) and the metal layer (37) are located in the cavity (25) to allow the magnetic lines of force from the magnetic layer (31) to removably secure the transparent layer (41) and the metal layer (31) in the cavity. In one embodiment, the lower holding layer (31M) has an opening (31(0) formed therethrough in which is located an advertising layer (33) which can be seen from above through the opening (39) and through the transparent lay- er (41). In another embodiment, the metal layer (37, 37M) and the magnetic layer (31, 31M) may be reversed in positions. In a further embodiment wherein the magnetic frame layer (31M) is bonded to the transparent layer (41) and the metal layer (37M) is bonded to the bottom of the cavity (25), one side of the frame (31M) is bonded to one side of the lower metal layer (37M) whereby the other side of the magnetic frame layer (31M) with the transparent layer (41) may be lifted from the lower layer (37M) and folded back to allow insertion or removal of the advertising layer (33).
