This is a complete farm animals set from the 1950’s. Each model # 619 farm would come with this set included. There were two versions of the model #619. One had a pond which is what this set would go with. All of these animals are made of rubber. Other sets were hard plastic with a rubber cow. As the catalogs do not describe the material of the animals I don’t currently know which came first, the rubber or the plastic set. The included sheets allow the purchase, by mail, of a cow or a set of pigs.
From my private collection.
