The floor advertisement apparatus is used in a cavity (25) formed in the floor (21) of a building. A lower holding layer (31) is located and secured in the bottom of the cavity. An upper holding layer (37) with an opening (39) extending therethrough has a transparent layer (41) secured to one side of the upper holding layer. The transparent layer and the upper holding layer are located in the cavity. An advertising layer (33) is secured to the lower side of the transparent layer within the opening for viewing from above. Both of the holding layers may be magnetic material or one can be magnetic material and the other one of metal attracted by magnetic lines of force for removably holding the upper layer to the lower layer when the two layers are located next to each other such that the transparent layer with its advertising layer is removably held in the cavity. In another embodiment, a support layer (71) is secured in the cavity. The transparent layer has a layer of adhesive material (171) secured to its bottom side defining an opening (173) which is covered by the transparent layer. The layer of adhesive material has a lower side adapted to be removably secured to the upper side of the support layer. An advertising layer can be removably located below the transparent layer within the opening or it can be secured to the bottom side of the transparent layer within the opening such that it can be viewed from above.
