Oriental items were popular in that period especially around the 20`s and 30`s !! But sadly there is really no way to determine much more than that !! New Orleans being a seaport,,has many items brought back from ocean voyages !! There is some wrinkling of the fabric which is probably from home framing !! I would suggest taking it to a professional frame shop or an art gallery that does framing and have it tightened/smoothed a bit and put back together with the original nails, backboard ect !! My opinion is that is from China or Japan and was framed just as an art piece !! This would fit with the depression era because of the lack of money and items like this were very inexpensive !! But even so people still liked their home to look nice !! During the depression they would put calendar pictures in frames or anything that was pretty !! I have seen floral fabrics framed for much the same reason,, to brighten the home during difficult times !!
