Kellogg's Pep Cereal

My dad remembers Kellogg's Pep better than me (he collected Pep pins when he was a boy), but it was still around when I was little, and was one I liked. It was quite similar to Wheaties. Would love to see some "heritage" cereals such as Post Oat Flakes and Kellogg's Pep return. I think they'd sell quite well. Haven't been able to find a box like the one I remember...Pep was more of a 1940s-1960s cereal, and it disappeared in the late 1970s. The box below is from the 60s.
