Old wooden window frame from an old barn or farm house here in Wisconsin... we get a lot of requests for old windows, but don't see them around much anymore.
It's a six light window, with six openings each 7 1/2" x 9 3/4". Measures 28" x 24" overall.
This one's a beauty, in primitive as found condition. It's never been cleaned up or varnished, and has some old nails with only add to the character of the thing.
