Topps's 1957 set contained Yankee great Mickey Mantle as card number 286. The card is known among collectors as the "ghost Mantle". Topps editors had long been expert at altering pictures to meet their needs. For example, the same photo of future major league manager Bob Kennedy appears in the 1954, '55 and '56 Topps sets. But the photo is airbrushed to show Kennedy in an Indians cap in '54, an Orioles cap in '55 and, finally, a White Sox cap in '56. The '57 Mantle card shows a posed shot of the switch hitting center fielder finishing a left-handed swing. The original photo apparently contained someone standing behind Mantle as he swung. When the card was assembled, the intruder was "blacked out", leaving a perfect silhouette, a "ghost", in back of the Mick. The outline is far more prominent and clear in some copies of the card than it is on others, inspiring debate among collectors as to whether Topps issued a corrected version, with the interloper better camouflaged.
