Lovely Decorated Page (Mat) from Victorian Album

This heavy cardboard page is taken from an antique photograph album. The page measures 8 1/4" 11 1/4". It has an domed rectangular opening measuring 5 1/4" x 3 5/8". The upper right side has a lovely landscape with a mountain stream. White flowers surround the photo opening. There is light soil. This would make an attractive interesting mat for a photograph.
