The trend spread, with supposedly Circassian women featured in dime museums and travelling medicine shows, sometimes known as "Moss-haired girls". They were typically identified by the distinctive hairstyle, which was held in place by the use of beer. They also often performed in pseudo-oriental costume. Many postcards of Circassians also circulated. Though Barnum's original women were portrayed as proud and genteel, later images of Circassians often emphasised erotic poses and revealing costumes. As the original fad faded, the "Circassians" started to add to their appeal by performing traditional circus tricks such as sword swallowing.
