In 1987 modern Parker struck gold with its Parker Duofold Centennial pen line to celebrate the 100th anniversary of Parker Pen Company in 1988. In many respects, this pen revitalized the company as a luxury brand. Plus, by basing the new design on vintage Parker Duofolds, it was the perfect touchstone for vintage and modern pen collectors. This marble blue pen is a Parker Duofold Centennial MKI. It likely isn't the 1988 model, as only 50 were made and given to notable individuals. However, it was a very early one as evidenced by its short pocket clip and 18k gold nib markings on the nib. Under the nib is an 83 on the feed, which means this was a medium nib.
