I like the mystery that comes with many of these old map puzzles. Looking at the Indian Territories, the Dakotas, the Dominion of Canada, Greece, Vietnam; searching for clues to the age of the map gives another meaning to the puzzle. The very first jigsaw puzzles were "dissected maps" and my oldest jigsaw puzzle is a map of England and Wales dated 1783. Map puzzles were made throughout the 19th and 20th centuries and continue to be produced in the 21st. In the United States, G.N. Tackabury, McLoughlin Brothers, Milton Bradley and Parker Brothers were all early mass producers of map puzzles. Many of the puzzles that I have came from one of these four manufacturers.
