Some kid had to snarf down a whole box of Corn Flakes for this card, in a year that didn't see any complete sets or poly bag retail packs offered by the manufacturer. Kellogg's 1971 baseball cards could only be found in cereal boxes, hampering today's supply. This Mint PSA 9 Clemente is a box bequeathed beauty with no sign of cracking and with the attachment nubs still very much visible (a good thing).
