This is an unused linen-era postcard picturing the Courtyard and Prison Rooms in the Cabildo at Chartres and St. Peter's Street in New Orleans, Louisiana.

On the reverse, the card notes, "Note the tiers and cells, and the wide galleries around them. The room, with the door standing open on the ground floor, is the cell in which the pirate LAFITTE was incarcerated after his capture by the Americans. Later on his services were accepted by General JACKSON and he participated in the Battle of New Orleans, where he covered himself in glory, subsequently receiving a pardon from the Congress of the United States.
