N300 card of Hall of Famer "Sliding" Billy Hamilton, graded AUTHENTIC by SGC.  The "alteration" referenced on the grading label is the addition of the word "BOSTON" over his original Philadelphia team affiliation, reflecting Hamilton's 1895 trade to Boston.  The card itself is clean, with a light crease running from the right edge toward Hamilton's chin, and typical chipping to the black edges of the card.  One of the more important and more desirable cards from the issue.
