Kellogg’s 3D sports card sets began in 1970, with both a baseball and football issue. This lot of 24 complete sets come directly from the factory, all in the original mailing envelopes…but were never mailed out. The 1970 Kellogg’s football set is very popular with collectors, with at least two dozen HOFers, including Gale Sayers, Dick Butkus, OJ Simpson, and Johnny Unitas. There should be countless PSA MINT 9 and GEM MINT 10 cards within, a regular treasure trove of fresh cards. Total of 24 HIGH GRADE Kellogg's Football sets in original mailing envelopes. Over 1400 fresh to the market cards!
