Most people don't know that in 1912, Hellman's Mayonnaise was manufactured in England. The Titanic was carrying 12,000 jars of the condiment scheduled for delivery in Vera Cruz, Mexico which was to be the next port of call for the great ship after New York City. The people of Mexico eagerly awaited the first delivery and were very upset at the news of the sinking. So much that they declared a national day of mourning which they still observe today.

It is known, of course, as Sinko de Mayo.
