Great picture. Would have been good candidates for 71 Topps Winners set.
Backs of 53 are a quagmire. Six cards were not issued 253/261/267/268/271/275. Cards 86-165 can be found with black or white bio info, except for 94/107/131/145/156 ( white only), while cards 10/44/61/72/81 have both, an anomaly in printing the sheets which caused the missing cards mentioned before
