World's Most Perplexing Puzzles by Charles Barry Townsend (1996, Paperback)

I always liked puzzles, especially ones didn't rely heavily on word plays to get the answer, but did involve analysis. Even better, these aren't overly replayed cliched puzzles, and there's a tremendous amount of variety. It's even refreshing seeing the pre-computer clip art that they use, it is perfectly consistent with the attitude of the puzzles inside.
