Exceedingly rare Pittsburgh Pirates 1902 opening-day invitation, to witness the raising of the National League Championship pennant, together with a 1902 opening-day pass signed by team owner Barney Dreyfuss. PSA has encapsulated the pass, grading the signature MINT 9. This invitation and pass are especially significant because they commemorate the club's 1901 league championship, which was the first in franchise history.  It should also be noted that Barney Dreyfuss' signature is one of the scarcest of all modern-day Hall of Famers because he died in 1932, but was not elected to the Hall of Fame until 2008. 

The fold-over invitation, which bears a colorful embossed Pittsburgh Pirates championship pennant at the top, is lettered, "The President and Directors of the Pittsburgh Base Ball Club request the honor of your presence at their Opening Game and raising of the National League Championship Pennant, Tuesday, April twenty-second, nineteen hundred and two. at three o'clock. Exposition Park. Allegheny."  Further text along the base reads "Cincinnati versus Pittsburgh" and "Admission by card only." The pass (card) that accompanies the invitation is made out to the "Hon. Alvin Evans" in black fountain pen and admits him to "Grand Stand/Exposition Park/Tuesday, April Twenty-Second/Pittsburgh Baseball Club." It has been signed in black fountain pen at the base by team president/owner Barney Dreyfuss. 

Pittsburgh won the National League pennant in 1901, which was the club's first league championship in franchise history. Therefore, the raising of the National League pennant on opening day in 1902 would be the first such ceremony that Dreyfuss ever presided over. Obviously, the significance the event was not lost on Dreyfuss or the club, as noted by the caveat on the invitation that "Admission by card only." The invitation (6x7") displays a single horizontal fold and is otherwise in Excellent to Mint condition. Accompanied by the original unaddressed mailing envelope (6.5x3.75"; EX-MT). The pass (4x2.5") remains in Near Mint condition.
