Modern Merchandising for Shipping Industry Speaking at the marine exhibition in New York, recently, Frank Lovejoy, sales executive of the Socony-Vacuum Oil Co. Inc., suggested that there is a real job of modern merchandising to be done in the shipping business today. Such a program entails showmanship, color, and _ publicity, Mr. Lovejoy pointed out. “Tell the American public your story—dramatize it in a way to appeal to the imagination,” he said. “The facilities are here to greatly expand activity. The shipping interests have just begun to tell the whole story. A big job of modern merchandising, re- plete with showmanship remains to be undertaken,’’ added Mr. Lovejoy.
