The earliest still banks were made from wood, pottery, gourds, and later, cast iron. Lithographed tin banks advertising various products and services reached their height in popularity between 1930 and 1955. The majority of these banks were miniature replicas of the products’ packaging.
Ceramic figural banks were popular novelties during the 1960s and 1970s. The most recent variation of still banks are molded vinyl banks resembling favorite cartoon and movie characters.
