These magnetic teak wood frame hangers make it simple to hang your maps, and allow you to scratch off your map without taking it out of a frame. The 19" frame will fit any of our 12 x 18 US maps with a half inch of overhang on each side. The 17" frame will fit our 16 x 20 National Parks Bucket List Posters. (Colors may vary in frames, but all are solid teak wood with a medium-light stain).
