Very cool item to frame and display. Shows Boston, Charleston, Massachusetts Bay and all the islands inside. Published by the U.S. Department of Commerce at Washington D.C., Coast and Geodetic Survey, dated September 28, 1953, revised 4/8/57, 26th edition. Size is 46 inches wide by 35-5/8 inches top to bottom. Folded is 23 inches by 19. See pictures for some wear, stains, and possible small tears. Note the condition issues at the top and middle. Inside a frame, these can be minimally visible. 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.
