Belonging to my neighbor's Grandfather, this pair of "Antique Art Deco Silver Two Sided Mother Of Pearl MOP Round Stud Button Cufflinks" made by Baer Wilde (B W) were purchased in the mid-1920s and worn occasionally through his death in 1976; my neighbor’s father received all his father's jewelry which was stored in a box in his closet. My neighbor’s father passed away in 2010 and he inherited the contents of his home, including these RARE, Hard To Find Stud Button Cufflinks. Getting ready to move to a smaller home, he has NO children and has asked me to sell these cufflinks for him; they come from a smoke-free, pet-free home. With a diameter of approximately 1/2 inch, they are Marked “Baer Wilde" on one side and "Kum A Part Regstd” on the other. These 1920s Cufflinks were masterfully handcrafted in gleaming Silver with iridescent Mother of Pearl and EXQUISITELY Simple detailing; the snaps are tight with no wiggle. An incredibly HANDSOME pair of Cuff Links, the workmanship is EXTRAORDINARY! MASCULINE Art Deco era jewelry also had a feminine beauty, making these DELIGHTFUL button stud snap link cufflinks IDEAL for a Man or a Woman; they fit through any normal/average size button hole. Sure to impress, they are high quality, finely crafted Kum-A-Part Snap Link Button Stud Cufflinks that are FABULOUS with a CLASSIC design and fine artistry that is exceptional and distinctive! Formed as the men's jewelry division of the Attleboro Manufacturing Company in 1908, Baer Wilde shot into popularity when they invented the Kum-A-Part cuff button in 1918. By the late-1930s, the company changed its name to the more well-known Swank Inc., which continues to sell men's accessories today. These cufflinks make it easy to see why the Kum-A-Part technology was so successful.
