Promotion Timing
I think we figured out when the 1960 Post Cereal sports-card promotion boxes were issued. Fred McKie worked with Robert Edwards Auction (REA) and obtained the cereal packaging date codes for each of the 9 1960 Post Cereal sports-card boxes that they are auctioning in their current auction. These dates are all in the same general time frame that Kirk Robinson's box is. Those dates were:
Kirk's Johnny Unitas Box January 20, 1960 (small Grape Nuts Flakes box)
REA boxes:
Johnny Unitas January 21, 1960 (small box)
Al Kaline January 26, 1960 (small box)
Don Drysdale January 8, 1960 (small box)
Frank Gifford January 21, 1960 (small box)
Bob Cousy January 21, 1960 (small box)
Frank Gifford January 21, 1960 (small box)
Mickey Mantle March 9, 1960 (large box)
Harmon Killebrew December 1, 1959 (large box)
Bob Pettit December 1, 1959 (large box)
So based on these cereal production dates, believe we can say with a high degree of certainty that these cards came out around the beginning of 1960.
