"Bankmark has been selected as the name for the new charge card system which is being introduced into the St. Louis trade area by Credit Systems, Inc., it was announced by James E. Brown, president. Mr. Brown said that a fourth bank - Brentwood Bank of Brentwood - has joined the system as a principle member. Others include Boatmen's National Bank, First National Bank in St. Louis, and The Mercantile Trust Co., N.A. who founded Credit Systems, Inc. The symbol, though modern in design, is ancient in meaning. The shape of early coins, which were hammered rather than cast, is portrayed by the overall appearance of the seal. Three pillars suggesting the bank, the merchant, and the consumer are prominent. The horizontal element above the pillars extends service to all."
