Hellman's mayonnaise was being manufactured in England in 1912 and the Titanic was carrying the largest single shipment of mayonnaise ever delivered to Mexico, with 12,000 jars scheduled for delivery in Veracruz. When the Titanic sank, Mexico was disconsolate at the loss of the anticipated mayonnaise shipment and declared a National Day of Mourning that continues to be observed each year on May 5th.
