This chart/map is shows from Cape Martin to Cape Nelson with an inset of Port Macdonnell and a section of the South Australian Coast line called the Great Australian Bight.
It would make a gorgeous piece to frame and hang on the wall. Perhaps you've sailed these waters?
Old charts are hard to come by as once out of production retailers are required to return stock to be replaced with new editions.
