Puzzles made of nearly identical pieces date back to the 19th. century sliced children's puzzles and the early 20th. century adult puzzles with straight line or crooked line cutting in grid fashion. Another obscure maker cut this unusual Perx Puzzle in the 1930's employing a diagonal grid pattern which created an entire puzzle (except the edges) of swastika-like pieces. Before jumping to conclusion that the maker must have been a Nazi sympathizer, it should be noted that the first definition of "swastika" in dictionaries is "an ancient cosmic or religious symbol..." and the swastika was used by several Amerindian tribes long before 1935 when the Nazi party adopted it. And the puzzle was most likely cut before 1935. Also,the cutter's saw was unable to cut square corners of a true swastika. Artist not identified.
