Pristine, white sign printed on heavy cardboard with bold crisp images advertises, “Attend the Big Opener - Have a ball at the ballpark with the St. Louis Cardinals” with their mascot catching a baseball in his glove. Created for the April 10, 1962 St. Louis Cardinals vs. New York Mets game at Busch Stadium, this was the first Major League game in history that the expansion Mets would play. Sign is EX-MT and easel-backed. The backing is in unused, like-new condition. Signed in blue sharpie on upper right corner by Stan Musial.
