Vintage pewter mug associated with the renowned Keen's Pipe Club of New York

Origin: This mug is a souvenir or member's item from the famous Keen's Pipe Club, which is part of Keen's Steakhouse, a historic New York City institution established in 1885.
The Pipe Club: Keen's is famous for its vast collection of churchwarden pipes, many belonging to prominent figures like Theodore Roosevelt, Babe Ruth, and Albert Einstein, who were members of the Pipe Club.
Significance: In the early days, members would store their fragile clay pipes at the restaurant, and a "pipe warden" and "pipe boys" would retrieve them when needed. While smoking rules have changed, the tradition of the Pipe Club and the collection of pipes continues as a historical and cultural landmark.
Construction: These mugs, like the one pictured, are typically made of high-quality pewter, often stamped with "Made in England, RAND English Pewter," indicating their craftsmanship and origin.
Collectibility: Vintage Keen's Pipe Club pewter mugs are considered rare
