The picture shows a view of the (2) Old Cereal Premium / Prize Dog Pin Back Buttons in this lot. These are believed to have been part of a series of dog pins that were used as cereal prizes in the 1950s. The cereal that used them is unknown. They each picture a dog breed in color and are marked as follows:
Eskimo Huskie Collie
They each measure 13/16'' wide and are in mint condition.
