This is a ballpoint pen made in 1973 at the request of Jackie Kennedy by Dupont, and it was also Dupont's first writing instrument. It was selected for display at the Museum of Modern Art (MoMA) in New York, and I heard it was priced around the same as the Montblanc 149 at the time. It's a heavy pen for its size. Overall, there are some minor scratches, but I think it's in good condition for its age. The twist mechanism works, but it's quite stiff, so I'm offering it at a bargain price. Material: Sterling Silver 925 Black lacquer on the clip, serial number present, sterling silver hallmark present. Length: Approximately 135mm Shaft diameter: Approximately 7mm Weight: Approximately 28g Accessories: None
