With 11 known alumni having played in the NBA, the medium sized public school in Philadelphia ranks sixth nationally in NBA players produced. Their most famous basketball playing alumnus is Wilt Chamberlain, arguably the most dominant player in NBA history. The towering Chamberlain averaged over 30 points and 22 rebounds per game in his Hall of Fame career. Chamberlain signed this ball in black marker and his signature is beautiful and clear, and projects abundantly well. He added his number, “13”, at the end of his signature.
