The floor advertising apparatus is used in a cavity formed in the floor of a building or the like. A thin lower layer is located and secured in the bottom of the cavity. A thin transparent layer is located in the cavity with its surrounding edge portion secured to the lower layer with adhesive. An advertising layer is located between the transparent layer and the lower layer below a viewing portion within the surrounding edge portion such that the advertising layer can be seen through the transparent layer when viewed from above. The advertising layer may be separate from the transparent layer or secured to its lower side. An opaque border is secured to the transparent layer in a position to cover the edge portion and adhesive such that the adhesive cannot be seen when the transparent layer is viewed from above. Double sided tape is used to secure the lower layer to the floor of the cavity. For installation in cavities formed in floors having conventional vinyl floor tiles, the total thickness of the apparatus is of the order of 1/8 of an inch.
