This is an incredible book for those seeking to improve their electronic aid-free navigation game. It is difficult to find these days. At the time of listing, it is the only copy offered on eBay.

This first-edition copy is in excellent condition with only minor edge-wear. I am happy to post additional photos, upon request.

Free US shipping via USPS Media Mail.

International shipping available via eBay's global-shipping program.

Thank you.
