Roger Clemens Baseball Card 1987 Leaf No. 51 ... Excellent Condition See Photos Includes FREE SHIPPING ... Released as part of the 1987 Leaf set, the Roger Clemens baseball card, No. 51, captures the burgeoning career of one of baseball's most dominant pitchers. At this point, Clemens was already a budding superstar for the Boston Red Sox, having secured his first Cy Young Award in 1986. The 1987 Leaf card, with its distinct blue border and Canadian-distributed nature (Leaf being a division of Donruss), presented a crisp image of Clemens in his pitching motion, a testament to his powerful presence on the mound. For collectors, this card represents a key piece from an era when Clemens was establishing himself as an undeniable force in Major League Baseball, well before the controversies that would later cloud his legacy.
