This must be quite a rare deck of cards as it is not fully described in Chapter 33 - Novelty Playing Cards from the Hochman Encyclopedia. I shall attempt to provide greater clarity regarding this deck here. First, the designer of this deck has his name misspelled in the encyclopedia as Castleton. It is, in fact, George Frederick Castleden who was a British-born artist who ultimately moved to New Orleans around the time of WWI and opened his own studio at 622 St. Peter St. This address appears on the sides of the OB (please see first picture of back of OB below). Second, the correct name of these cards is not Mardi Gras cards but, instead, Vieux Carre Playing Cards. The term "Vieux Carre" means Old Square in French and is the French Quarter, the oldest neighborhood in the city of New Orleans and a popular tourist destination. This deck is so titled because, to quote from the extra joker (please see second picture below), it is "A souvenir of the Old French Quarter of New Orleans, sketched from existing sites of historic and romantic interest by the noted artist Geo. F. Castleden in collaboration with Lewis A. Clapp." Each of the 52 cards contains an oval scene in black for the spades and clubs and in red for the hearts and diamonds. Samples of 3 of these cards are shown below followed by the court cards from the diamond suit. The court cards in the major suits, spades and hearts, are identical, showing the Mardi Gras King and Queen, while the jacks show a pirate. The court cards in the minor suits are also identical and essentially the same as the major suits but there are slight changes made to them. The following is a list of the scenes shown on each pip card.
AS - The Cabildo
2S, 2H - Duelling Oaks - City Park
3S, 3H - Stairway - House of the Two Sisters
4S, 4H - Old Louisiana State Bank

3D, 3C - Doorway - The Absinthe House
4D, 4C - Courtyard - Gov. Claiborne's Res.
5D, 5C - The Napoleon House
6D, 6C - Old Mortgage and Deeds Bld.
7D, 7C - Saint Louis Cathedral
8D, 8C - The Paul Morphy House
9D, 9C - The Haunted House
10D, 10C - Courtyard - The Cabildo
As can be seen from this list, the scenes on the pip cards are repeated with the exception of the Ace of Spades and the Ace of Hearts making a total of 21 different scenes from the French Quarter plus the 3 different court cards. The card backs show a reversible image of Jackson Square with a one-way title Vieux Carre. There is an accent over the letter "e" in "Carre." The backs came in either red or blue. The entire deck would have consisted of 54 cards in total with a joker and an extra joker but, sadly, my deck lacks the joker. Should any other user of this website have an example of this deck in their collection, I would love to see a picture of this card. This deck was printed in New Orleans by Tropical Prtg. Co., Inc. in 1930 and is copyrighted by G.F. Castleden on 12-1-30. Mr. Castleden also published a series of postcards showing his artwork of various views of the French Quarter which he sold to tourists.
