Jig of the Week Puzzle No. 20. 1932. This was bought at a Salvation Army Thrift store in Cambridge Mass in 1978.
This puzzle is not uncommon on the internet. However, one picture that we found on page 71 of the Questions & Answers Forum of PuzzleHistory.com, captured and saved here as washvrn.jpg has different corners from my copy. My copy has sort of rounded corners, while the picture found on the net has square corners (with irregular top and bottom edges).
