Date Dec. 29, 1988.A device for the visual presentation of visually combinable objects which are reproduced on two separate boards which are capable of guided movement relative to each other. One board has an image of a main object with an aperture at a desired location, such that a second object shown on the second board may be viewed through the aperture. For example, the main board may contain a picture of an automobile with apertures where the wheel hubs are located. The second board may contain an assortment of wheel hubs. By manipulating the guide in various directions, different wheel hubs can selectively be made to appear in the aperture on the main board, thereby showing the automobile with different wheel hubs for comparison purposes.
