Abstract
A display device has two interlocked contrasting elements. A first element is of a first color, and has a top surface configured to resemble desired indicia, e.g. one or more letters or numerals. The first element also has a bottom surface which includes a plurality of first locking members. A second element has a plurality of second locking members which interlock with the first locking members, and is of a second color. The second color preferably contrasts with the first color. The interlocking action of the first locking members with the second locking members serves to interlock the two contrasting elements, thereby providing a good mechanical locking action therebetween. In a first embodiment, the first and second elements together form a generally flat top surface, while in a second embodiment, the two elements are of different top levels, so that the indicia may be either raised or recessed with respect to the background.
