Here it is. The last card I needed to complete my 2011 Tristar Obak set.
The card celebrates Roger Connor hitting the first recorded grand slam in major league history. Connor, a 1976 Hall of Fame inductee, accomplished this on September 10, 1881. Connor was also the MLB all-time home run leader prior to Babe Ruth. He had hit 138 round-trippers over his car. Ruth eclipsed this number on July 18, 1921 as a 26 year old.
