This is a 17'' x 22'' mat with a 13 1/2'' x 12'' opening to showcase the image of the Piazza Del Campidoglio, the most important of Rome's seven hills. A tissue overlay describes the piece. The mat is soiled, but the image is in very good condition. This came from a portfolio from the early 1900's.
