Vintage Cast Iron Black Americana Hubley? Toy Figures Banjo Player, Mammy +
Have seen these referred to as having been produced by Hubley but they are not marked so I cannot guarantee that. Paint chips. I believe they date from the 1920s or so. There is the old man playing the banjo, mammy, little girl, and dancing boy. The tallest is 3 1/4\".
