The sender is a big supporter of the Louisiana State University(LSU) Tigers American Football Team. LSU is located in Baton Rouge and was founded in 1860 as the Seminary of Learning of the State of Louisiana.

The sender said I might enjoy the Cajun humour on this card. Cajuns are usually described as the descendants of the Acadian exiles who were deported during   Le Grand Dérangement - Acadian forced deportations from Nova Scotia. People in Louisiana frequently use Cajun as a broad cultural term without necessitating race or descent from the deported Acadians. French colonists were already living in Louisiana prior to the Acadian deportation. However, most Acadians can trace their ancestry back to approximately 50 families who were living in Port Royal, Acadia (now Annapolis Royal, Nova Scotia) in 1671. Most Cajuns can trace their ancestry to areas in Nova Scotia, New Brunswick, Prince Edward Island,  Québec , and Maine.  Cajuns have become famous for their French dialect and have developed rich culture including folkways, music, and cuisine.
