Scott's Specialized is the Bible of US Postage Stamp collecting. In 1935, with the help of CS&CSS members including, Dorsey F. Wheless, and W. L. Kinkead, first president of our club, Christmas Seal were added to The Scott Specialized Catalogue of US Postage Stamps. Check Lists of US National Christmas Seals first appeared in Scott's Monthly Journal, May, 1928.
