The Martinique 3’X5′ World “snake flag” features a white cross on a blue field with a white snake in each quarter. These are fer-de-lance vipers native to Martinique. The snake flag is locally considered an insult and not available for sale or trade locally. It is mainly, erroneously used as a courtesy ensign by yachtmen, who should hoist the Tricolore civil ensign instead, as this unofficial flag has no value. Martinique, an overseas territorial collectivity of France located in the Caribbean, has no flag with an official status other than the French national flag.
