This chart/map covers Frankland Islands to Lizard Island in Queensland.
As shown in images, this is charted, and has residual tape on the right hand edge.
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.
