Puzzle from "The Penguin Dictionary of Curious and Interesting Puzzles"

Here is an interesting puzzle from “The Penguin Dictionary of Curious and Interesting Puzzles” by David G. Wells.  This would be anther really swell place for Amazon.com to place an ad.  You will probably need to print this puzzle and cut out the pieces.  I will post the solution tomorrow.  (And, I will save you a trip to the library to look up the answer – Mr. Wells forgot to put the solution in his book.)
