PEP was a brand of whole-wheat breakfast cereal produced by the Kellogg Company in USA, first seen on shop shelves in 1923.

In 1945, 1946 and 1947, the Kellogg Company inserted a give-away collectible in the form of pinback buttons into specially marked boxes of PEP cereal. PEP pins included U.S. Army squadrons as well as comic book characters published in newspapers at the time. Below we see an example of a PEP cereal box promoting the buttons.

There were five series of comic book character pins released, with 18 different pins in each set. The Superman button was included in all five series, hence 86 unique comic character pins were released.

The Phantom was also featured on a PEP pin, found in the 3rd series by the Kellogg Company in 1946. The front and back of the Phantom pin can be seen below, with the front of the pin showing a profile image of the Phantom as illustrated by Ray Moore.

Each pin inserted in a specially marked box of PEP cereal was released in a clear plastic wrapper. Below we see the Phantom PEP pin still in it’s original wrapper.

A Beanie Cap was released by Kellogg’s to display your PEP pin collection. Below we see advertisements for the Beanie Cap by the Kellogg Company, plus an example of the Beanie Cap itself covered in PEP pins.

Advertisements were also seen promoting the PEP pins, usually displayed in retail outlets where the breakfast cereal was sold.
