The International Trade Mart was a New Orleans-based organization promoting international trade and the Port of New Orleans. The organization was founded in 1946, and merged with International House in 1968, when it was renamed to World Trade Center New Orleans. After World War II, New Orleans businessman Clay Shaw returned to New Orleans where he became a founder of the International Trade Mart (ITM). From 1947 to his retirement in 1965, Shaw ran the ITM as a managing director.
