The Library of Congress has on its web site a selection of Spalding Base Ball Guides from 1889 to 1939.
The title quote is from the “Editorial Comment” article near the front of the 1939 guide, ampoule which ends with the statement “The new century begins with the promise of a rare battle in the younger league, online and with just as good a one to establish supremacy in the older. May the best club win, and then the battle for the one grand championship which will settle all—for another year.”
