Other news, sports and advertisements of the day. Complete in 56 pages, this is the rare rag edition that was produced on very high quality newsprint, with a high percentage of cotton & linen content, allowing the issues to remain very white & sturdy into the present. Given the subscription cost, libraries & institutions rather than individuals were the primary subscribers of these high-quality editions. A few small binding slits along the spine, very nice condition.
