Much more than just the man who moved the Dodgers from Brooklyn to LA, Walter O'Mallley also owned the franchise for three glorious decades, was the most powerful man in baseball during the 1960s, created the unchallenged business model for sports franchises, and changed the way teams did business. An extremely rare HOFer single, only about five O'Malley exemplars have been offered at major public auction in the past twenty-five years. This specimen presented here has been ensconced in a top tier collection since the early 1990s. NRMT "MacGregor Official Little League" baseball displays an amazingly large "Walter F. O'Malley" signature perfectly placed across the sweet spot in bold 8.5/10 felt tip. While the sphere is not a Major League issue, the autograph is probably the best in the hobby. LOA from PSA/DNA.
