The cards in this 609-card set measure 2 1/2" by 3 1/2". The 1967 Topps series is considered by some collectors to be one of the company's finest accomplishments in baseball card production. Excellent color photographs are combined with easy-to-read backs. Cards 458 to 533 are slightly harder to find than numbers 1 to 457, and the inevitable high series (534 to 609) exists. Each checklist card features a small circular picture of a popular player included in that series. Printing discrepancies resulted in some high series cards being in shorter supply. The checklist below identifies (by DP) 22 double-printed high numbers; of the 76 cards in the last series, 54 cards were short printed and the other 22 cards are much more plentiful. Featured subsets within this set include World Series cards (151-155) and League Leaders (233-244). A limited number of "proof" Roger Maris cards were produced. These cards are blank backed and Maris is listed as a New York Yankee on it. Some Bob Bolin cards: (number 252) have a white smear in between his names. Another tough variation that has been recently discovered involves card number 58 Paul Schaal. The tough version has a green bat above his name. The key Rookie Cards in the set are high number cards of Rod Carew and Tom Seaver. Confirmed methods of selling these cards include five-card nickel wax packs. Although rarely seen, there exists a salesman's sample panel of three cards that pictures Earl Battey, Manny Mota, and Gene Brabender with ad information on the back about the "new" Topps cards.
