The 1948 Leaf boxing set is one of the two post-World War II boxing sets issued by a major gum manufacturer. It consists of 49 different regular issue cards plus the T206 Wagner of boxing the Rocky Graziano. Printing quality is the biggest problem with 1948 Leaf cards. The company was notorious for press mistakes. We are pleased to offer a variety of cards representing the “best” of Leaf’s quality control: If the pressman at the Leaf factory had an especially bad day (perhaps the result of an especially good night before) he might accidentally print the card backs upside down and then also accidentally cut the cards with the back of the sheet facing up. The result would be cards with well aligned backs and miscut fronts. And so we are able to offer five examples of a double error: Harry Forbes Arturo Godoy Lou Ambers Kid Chocolate and Tony Christofordis.
