The 1971 Kelloggs was a high demand set back then, and the only Kelloggs issue that didn't have a mail-in offer for the complete set. As Howie mentioned, the ONLY way to get them was to buy the cereal that year. I remember buying a complete set from Chicago dealer Bob Solon for $75 that year, that was HUGE money for a 12 year old. I worked 40 hours at $2 an hour as a groundskeeper to pay for that set
