A flag is defined as a piece of fabric (frequently rectangular or square) that has distinctive designs and colors.
Flags can be used for many different purposes including national identity, signalling, messaging, advertising, or simply for decoration. The study of flags is known as “vexillology“.
Marine Signal flags are particularly important at sea. Understanding their meaning and message can be the difference between life and death. The rules and regulations for the flying of flags on the water are strictly enforced.
The most expensive flag ever sold was is an American Revolutionary War Battleflag (1776–1779), which was bought on 14 June 2006 for $12,336,000, at Sotheby’s in New York, USA.
A pirate flag, known as a “Jolly Roger” or ‘skull-and-crossbones’, was an invitation to surrender. It carried the implication that those who surrendered would be treated well.
