Waite-Thresher Sterling Thimble with blue enamel fylfot.
US$469.12; 18 bids starting at $9.99.
22 March 2007.
This thimble was manufactured in the early 1900's before the decoration it bears connoted egregious hatred and barbarism. The fylfot, or swastika, had long been a decorative motif throughout the world. It was on all sorts of things: clothing, jewelry, religious statues, buildings. On the sides of barns, even. Just a swirly decoration. Now it's just ugly. I didn't want to bring pain to someone just surfing by, checking out benign little thimbles, so the picture isn't on this page, but if you want to see the thimble, you can click on the link above.
