Antique wooden shadow box picture frame; the Currier & Ives Midnight Race on the Mississippi is a vintage reprint - not an original; unsigned - we do not know the maker - probably mid to late 19th century - constructed with square nails; total of actual frame measures about 17-3/8" X 21.5" and just shy of 1.75" thick; glass portion for image is about 14" X 18" (dollar bill shown in image for size comparison only).  Imperfect, antique, pre-owned, used condition - some surface wear and scratching, and it could use some new prongs or nails to secure the glass and the image - they are not that tight (please see photos).  The print has a few tears and water damage.  Backing is cardboard.
