By the mahogany frames and design, this pair of framed duck tile designs were probably made in the 60's. The characters on the signature on the bottom tile looks Chinese (not Korean or Japanese), but there's a tag on the back of each that reads "CDGC, Hand Decorated Quality Imports, Japan" and another that reads "Patent No. 492647, Made in Japan" There's a reddish tinted burlap background behind the tiles. Dimensions listed are for one of the frames. See
