Only the wood part is the frame !! Did it or does it have a glass on front ?? If so it could be a watercolor or something similar on paper !! It could be a magazine or calender page that was framed !! How they are done is to lay the frame down face first, then a glass, then matting, then picture is centered and secured, sometimes a thin piece of cardstock on that then dust cover is glued in place !! And last a heavier piece of cardboard as backing before the tacks are added !! It appears to be something that was done simply for an art piece to use as a decorative piece !! Since it isn`t signed and is primitive in technique it would not be worth a lot and water damage lessens that value. Could be from 20`s or 30`s !! Would have to guess at that since nothing to date it by !!
