Very cool item to frame and display. Lake Huron's Georgian Bay in it's entirety. The detail and colors on this are incredible. Published by the Canadian Hydrographic Service, No. 2201, 1972 with notice to mariners corrections to 1975. Size is 40 inches wide by 39 inches top to bottom. See pictures for some wear, stains, and possible small tears. This is an authentic original chart, so it'll have writing on the outside, stamp marks, some nice vintage colors, and slightly tinted paper patina. This will be shipped flat in a 20 x 27 heavy board envelope.
