He orchestrated his Philadelphia Athletics through two dynasties and provided the gentle, but capable hand of navigating his franchise through a half-century of quality diamond performances. And though Connie Mack was always receptive to an adoring public, his autograph (a captivating work of art in itself) remains a hobby treasure of the highest order.
