Offered here is one of the most historically significant cards in the hobby—the 1916 M101-5 Babe Ruth Rookie Card with Blank Back, graded PSA 4. This early image of the 21-year-old Ruth in his Boston Red Sox uniform captures the Bambino before he revolutionized the game with his bat. Issued during his first full season in the majors, this card marks Ruth’s formal cardboard debut and is widely regarded as his true rookie. With a classic pitching pose and crisp print detail, this example retains exceptional eye appeal for the grade, offering strong centering and clean borders. A cornerstone artifact that stands as a pillar in any elite prewar collection.
