I’ve been buying old 1945-46 Kellogg’s PEP cereal comic pinback buttons. I’ve seen them around the internet for very high prices, but I got a good deal on thse. I purchased them one or two at a time. They are quite small as you can see – 13/16″, lithograph print on front with Kellogg’s PEP cereal stamp on the back.
Pep was a brand of whole-wheat breakfast cereal produced by the Kellogg Company, and introduced in 1923.
I got the Pop Jenks from the Harold Teen comic strip and Andy Gump from one guy, he sent me the Pop Jenks instead of the Andy Gump, which I ordered, and when I let him know, he told me to just keep ‘ol Pop, too, rather than send it back. Popeye and Olive came as a set and Superman and Smokey Stover came separately. I am purchasing more as we speak.
I got this Moon Mullins button, too. Just paid for it ($3.99), it’s in the mail on its way!
Someone is selling the whole set, I think 86 pins, for $799.00. That comes to over $9 a pin but I’m getting them for half that purchasing them one at a time, which sort of makes it more fun and more of a sport, you know, tracking them down one by one.
