Puzzle Craft
by Stewart Coffin
(published by Stewart Coffin 1985 - 100 pages and 1992 - 80 pages, soft cover)

The 1992 edition used the same cover as the 1985 edition; the inside of this cover is shown above, along with the prefaces to both editions. These are predecessors to the Oxford U. Press Coffin book, and electronic versions are available on the CD version of that book.
