This is a high-quality mechanical souvenir from the 1893 World's Columbian Exposition in Chicago, designed in the classic "Rondelet" bottle style. The heavy brass casing features a finely engraved portrait of Christopher Columbus. While Rondelet-style bottle corkscrews were popular fair souvenirs, this specific specimen is distinct for its 5-view Boston-themed Stanhope micro-viewer embedded in the neck.
The tool features a threaded brass Rondelet body that unscrews to reveal a high-carbon steel corkscrew. The handle is formed by threading the corkscrew through the center of the bottle body for leverage. The neck of the bottle houses a multi-view Stanhope lens that reveals five distinct, captioned scenes: the Old State House, Bunker Hill Monument, Massachusetts Institute of Technology (MIT), the Paul Revere House, and Christ Church.
The brass exhibits a rich, uncleaned mustard patina consistent with its 130-year age. The mechanical threads remain smooth and function perfectly, and the steel corkscrew is sharp and well-preserved. The Stanhope lens is in excellent condition—clear, centered, and offering a bright view of all five historical landmarks.
The 1893 World's Fair was a showcase of Victorian innovation, and the Rondelet corkscrew remains one of the most recognizable mechanical souvenirs from the event. This piece represents an interesting crossover between Chicago Exposition branding and Boston historical interest, likely created for the active tourist trade that traveled between major American hubs during the Exposition year.
