In the U.S., Banthrico started producing diecast promotional model car banks in the late 1940s for the banking industry. These coin-banks were available as gifts to customers who opened a new account and had a slot in the bottom to put their spare change. Usually the bank's name and address was painted on the roof of the car. Banthrico models were also painted in authentic Big Three colors and used as "paint chips" so dealers could gauge the upcoming colors on real models. These primitive promotionals included Buicks, Cadillacs, Lincolns, Packards, DeSotos, Chryslers, Dodges, Ramblers and the more common Chevrolets and Fords.
