antique gold wood picture frame, original plank back frame w/ square nails

Antique wood picture frame with gold paint over gesso decoration, fastened at the corners with square cut nails, and backed with a wide plank. It measures 16 1/2" x 13 1/2" over the framed area.

We have no glass for this, and it's not in perfect condition - there's some chipping to the gold and the gesso, and the corners are a little loose.
