Rolly Crump's design for the enchanted Romani wagon was later reworked for Madame Leota's Vardo.
The Vardo serves as a form of small gift-shop located outside of the Haunted Mansion while the more legitimate and expansive gift shop, "Port Royal Curios and Curiosities" is located in one of alleys of New Orleans Square.
The cart is decorated to be the Vardo which Madame Leota would have used while still alive in New Orleans, alluding towards her backstory being that of a traveling Romani medium in the late 18th-19th century. The writing on the cart references her having performed seances, crystal gazing, performing parlour tricks, brewed potions, selling mysterious tomes and casting magic spells. - Haunted Mansion Wiki
