Very cool item to frame and display. In Lake Ontario, this shows Cobourg, Presquile Bay, Brighton, and more. Published by the Canadian Hydrographic Service, No. 2061, 6th edition, July 1972. Size is 37 inches wide by 29-1/2 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.
