Original 1967 Houston business trade magazine vintage ad for the HOUSTON NATIONAL BANK.  Main office was located in the Tennessee Building at Milam and Lamar Streets, Houston, Texas. Would your wife want the Businessman's Bank as co-executor? Yes. Naming Houston National Bank as co-executor and co-trustee in your will is a wise and thoughtful decision. ​This old one page financial magazine advertisement would display beautifully matted and framed.
