PSA has only graded 71 Connie Mack Book Cards, so complete sets are ultra-scarce; this raw one was auctioned off in May 2000.
About the set, PSA writes, “The 1951 Connie Mack Book baseball card set, as the name implies, was issued in conjunction with the Hall of Fame manager’s book, “My 66 Years in the Big Leagues.” Consisting of only four cards – Connie Mack, Christy Mathewson, Babe Ruth, and Rube Waddell – each piece measures 2-1/4″ by 3-1/2″ and was issued in a folder entitled “Four Mighty Heroes.” Each black-and-white card features a player photo against a white background and his name identified in print. The reverse has that athlete’s career statistics and an advertisement for Mack’s book. Not surprisingly, the value of Ruth’s card in Near Mint condition is almost twice that of the other three cards combined.”
Sports Collectors Daily reported that “the cards were packaged together in a folder likely sent to reviewers and others in hopes of garnering publicity.”
In May 2021, REA sold one of those folders and an SGC 1-graded Connie Mack card for $114; here are the front and back of the booklet.
Don’t let that sales price fool you; in the fall of 2022, REA also sold a PSA 9-graded Babe Ruth for $4800; hello icon prices!
