ABSTRACT:
The present invention is directed toward a substantially planar business communication assembly that has one or more ablated recesses or depressions which are created through the use of electromagnetic radiation. The assembly preferably includes first and second portions that are joined to one another to form a composite construction. The business form is typically provided with an ablated depression in one of the two portions. The depression has a depth that is sufficient such that when a removable element is placed within the depression the surface of the removable element is substantially planar with the surface of at least one of the surfaces of the portions used to make up the assembly.
