The 1961 Fleer set gave Wilt a rare second card — #47, an “In Action” shot that pairs with the #8 rookie as the connoisseur’s companion piece.

Where the rookie is the portrait, this is the motion: Chamberlain doing on the floor what no one his size had ever done.

The quiet second half of the set’s defining pair.

Collectors chasing the complete Wilt story want both — and the In Action is the harder of the two to find truly clean.
