Vintage USA children's sectional puzzle

Hope these 2 photos are enough. I can find no identifying marks, but the puzzle pieces and holder seem to be made of balsa wood, very light almost white. The states with identifying capitals are in sections and I even noticed it shows Canada at the top. Hawaii and Alaska are at the bottom in a long rectangle oval. I love old children's items and could not let this one pass me by. Hope someone has seen one or can identify it. It is in excellent shape. Thanks so much for your thoughts and time!
