1972 Cadillac Advertising Piece - A Hi-Fidelity Mat by Reilly-Lake Shore Graphics of Chicago, IL!  This item features etched pictures of the Cadillac Sedan De Ville and Eldorado Convertible, along with copy that lists the design changes for the 1972 model year.  I am not sure how this piece was to be used, but I suspect it was distributed in press kits at the beginning of the model year.  It measures 6-3/8" x 7.5" and is in very nice condition (see condition description and pics).
