Legendary Auction Corn Flakes Set ??

[71buc]

The inserts for the sports illustrated posters were in fact two sided. One side featured the NL players and the reverse displayed the AL players. I seem to recall that the posters were displayed for sale in a large cardboard box. I know the rolled up posters tubes had the item number number printed on an adhesive strip across one end of the tube. Customers could look at the pictures on the display box and then select the corresponding numbered rolled up poster tube from the box. I do recall in the early 70s looking for the Clemente on multiple occasions at a local sporting goods store in Tacoma. I settled for Rose and Yaz. I have no idea why I didn't simply order it from the magazine but I remember the the disappointment clearly.

I too had never heard of Champion Corn flakes. Was it a Post or Kellogg's product? It seems odd to me that either company would use a Sports Illustrated Action image for a card. I can't recall either company producing action cards during that time. A web search for Champion Corn Flakes was of little help. However, it revealed the football set which has been graded by PSA and is listed in their registry. I wonder if the same product numbers and images were also used for the sports illustrated football posters? Perhaps these hand cut cards could have been cut from Sports Illustrated product display boxes? That could explain the card stock and the blank backs. This is merely a hypothesis and certainly not meant to be misconstrued as a statement of fact.
