The Chicago Cubs superstar launched a third inning blast into the seats at Wrigley this day, much to the joy of the bleacher bums who came out to watch their team crush the crosstown ChiSox by a score of eight to four.  Blue gamer exhibits fine wear from this milestone homer, with all the little details you look for in a Sosa gamer.  Logo patch over heart; “Sosa 21” on verso.  Captain’s “C” and “National League” patches on left and right sleeves respectively.  Sleeves with Sosa’s personal elasticized customization.  Tail tag is “Majestic Authentic [size] 48,” and Sammy has written the date (6-14-02) on it in blue marker with his initials.  Note that the tagging is not typical of Cubs jerseys, as Sammy purchased his from the pro shop instead of through usual channels. But have no fear—not only did Sammy initial the tagging, and sign the back in perfect sharpie: “Sammy Sosa 21, HR 475, 6-14-2002, Game Used 2002”, but he also signed the included Letter of Authenticity, issued by the company that holds Sammy’s exclusive memorabilia and autograph contract.  You can’t beat that!
