Vintage Navigation chart Houghton Higgins lake

Up for auction today is my vintage navigation chart of Houghton and Higgins lake. It was printed in Detroit Mich. on May 13, 1968. (1st edition). There is some staining on the covers and yellowing of the pages. There are some bends but no rips, tears or writing. There is color on the cover and almost every page. It's size is 11"x 14" and contains 15 pages. The book separates the lakes into different areas and bays and contains different landmarks from the areas. Every other page contains written descriptions of the plates and also describes the different landmarks and locales. There is advertising throughout the book, with many of the establishments now gone. It is a nice piece of history from 58 years ago. Shipping on this item will be 12oz. and will be paid by the auction winner.
