Abstract
A cavity is formed in the floor of a building for receiving the floor type advertising apparatus. A lower holding layer of magnetic material having an opening formed therethrough is located and secured in the lower portion of the cavity. An upper holding layer of magnetic material having an opening formed therethrough is attached to the lower side of a transparent layer and both the transparent layer and the upper holding layer are located in the cavity to allow the magnetic lines of force from the holding layers to removably secure the transparent layer and the upper holding layer to the lower holding layer in the cavity. A support layer is secured to the floor of the cavity within the opening of the lower holding layer for supporting an advertising layer. One side edge of the upper holding layer is bonded to one side edge of the lower holding layer whereby the other side edge of the upper holding layer with the transparent layer may be lifted from the lower holding layer and folded back to allow insertion or removal of the advertising layer.
