Manufactured by the United States Rubber Co., this 1930 Tiger rubber-core ball with studs inside circles is in gem-mint condition. This ball is still in its original yellow cellophane wrapper that has never been fully opened. The beautiful, original yellow paint is all there and it still has its original full luster, looking just like it did the day it was made. What a find! Also note that the ball is marked "Tiger" and not "US Tiger" which is what is typically found on the white version.
