Product Description From Retro 1951: Celebrate Americas National Mammal with the officially licensed Smithsonian Bison: Standing Strong Tornado Rollerball. Inspired by the Smithsonians Bison: Standing Strong exhibition, this pen celebrates the remarkable resurgence of the American bison and its significant place in our nations history. Bison have shaped the American landscape for centuries and remain a powerful symbol of strength, resilience, and determination. More than 100 years ago, living bison grazed on Smithsonian grounds near the Castle as part of early efforts to help preserve the species. In 2026, in honor of the nation’s 250th anniversary, bison returned to the National Mall in a bold new form, with bronze sculptures of three larger-than-life bison installed permanently at the entrance to the Smithsonian’s National Museum of Natural History. This Tornado twist-top pen features bison acid-etched into a stonewashed copper barrel, creating a timewornappearance reminiscent of a vintage American coin. Stonewashed pewter trim complements the rugged finish, withSmithsonian etched into the top ring and the iconic sun logo adorning the top disc. Packaged in a commemorativeRetro51 tube, the Bison: Standing Strong is a fitting tribute to an iconic American animal and the enduring spirit itrepresents.
