This book was compiled for those who find enjoyment, entertainment and relief from worry in solving mechanical and manipulative puzzles and for the recreational leader who uses puzzles as a leisure time activity. A few can be purchased—but by including such information the title of the book would be misleading; and furthermore it's more fun to make than buy them.
This book is a facsimile reprint and may contain imperfections such as marks, notations, marginalia and flawed pages.
