Boudoir fans made from a single ostrich feather became popular as playful accessories, serving more as elegant adornments than practical tools for cooling oneself. These fans often featured two-tone designs and were cherished for their aesthetic appeal. Collectors highly value these fans, especially those in such pristine condition, as they represent a bygone era of glamour and sophistication. Finding one in an uncommon color like orange, and in excellent condition, is indeed a rare and delightful discovery.
