I Never Heard of Kellogg's Pep Cereal

I saw this article on Sports Collectors Daily - 1937 Kellogg's Pep Cereal Stamps.  The article mentioned that this cereal was sold until the 1970s, but I don't remember it at all.  It was said to be a rival of Wheaties, so the stamps promotion makes sense since Wheaties was using sports giveaways to sell cereal during the 1930s.

I've seen these items on ebay but I never clicked to learn any more about these stamps.

This article was worth reading.  Will I ever attempt to get these?  I don't know how much I am going to branch out into other Kellogg's sports-related items.  That might work if I end up getting all of the 1970 - 1983 cards.

I was disappointed to find out that there were few golfers and no track and field athletes.
