This is arguably the most desirable book on antique diving helmets. Titled Helmets Of The Deep by Leon Lyons, this specific example is a hardcover presentation edition. Only 900 of these were printed, with this example being number 5 along with a personal inscription and date! The book is full of hundreds of color photos of some of the rarest and most interesting diving helmets documented by Mr. Lyons up to the late 1980s.
 
This specific example is complete with a dust jacket and is in like-new condition. The dust jacket does have a clear Duplex book jacket protector over it that can be removed if so desired. It is a fantastic reference book and great fun to peruse.
 
Of the few Presentation Editions we have sold, this one is the best example we have handled.
