One of my favorite finds! I believe that these 'ribbed' buttons were made by the Weber Button Co., of Muscatine, Iowa, sometime after 1904. I am estimating the age to be from the 1910's, but this is my best estimate-- the buttons could be older or newer.
Never used set of 12 matching buttons, each measures approximately 5/8" in diameter. The overall card measures approximately 3 1/2" by approximately 2 1/2". Buttons are still securely sewn to card. The only flaw is that the punch for hanging is right in the middle of the company logo... but I still believe that these were manufactured by Weber Button Co. The tagline at the bottom of the card reads "The World's Largest Button Market." You are not going to find many of these in this amazing condition!
Be aware that this is a vintage, used item, so the item may have some imperfections. Any glaring or noticeable imperfections will be included in the listing description. And, the coin shown in the photo above is not part of the listing-- it is simply pictured for purposes of scale.
Buy with confidence! I've been buying and selling antique and vintage jewelry and other accessories for years and these earrings have been a part of my personal collection. It's time for someone else to enjoy them!
