Charles L. Hart lived in Christchurch, New Zealand. In the early 1930s, he found himself out of work and in poor health. Worried about how his wife would support hereself after his death he cut about 50 puzzles so that his wife could run a lending library of jigsaw puzzles and make some extra money. He died in 1936 but his wife never set up such a business. The puzzles remained in the family home until the 1990s when they passed first to Hart's son and then grandson who found me through the internet and sold me the puzzles. The puzzles were all asembled in their original cellophane from the 1930s, never having been used.
