This chart/map focuses on the River Thames from London Bridge to Woolwich.
As shown in images, this chart shows some age-marks, small tears and yellowing.
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.
This one has handmade corrections written in the late 60's/early 70's.
