Any card that reaches the level of PSA 9 MINT from the centering-challenged 1961 Fleer basketball series is indeed a rarity, but when it's a rookie card of Wilt Chamberlain, it's a museum-quality piece that defines an advanced collection! While his mainstream rookie card stands as one of the most important pasteboards that Fleer ever produced, regardless of sport, this "In Action" example is also a rookie card yet continues to fly under the radar with collectors. The "Big Dipper" is shown throwing down on some poor stiff, sporting incredibly bold colors and high-quality MINT to GEM MINT corners to enhance the virtually perfect centering, a phrase rarely used for this series. Whether it's for a move on the PSA Set Registry or another rare piece for a world-class collection. This beauty is simply magnificent!
