Edith Sandor (Edith Kleinbarth) is a circus performer from Finland who performed as a juggler in the 1940s and 1950s. She wrote a book in 2007 titled Ballerina On Horseback.
This is a metal “horn” with an elastic chin strap and four small tape-wrapped wooden rings, which were tossed high into the air and caught on the horn, which was worn on the head. This is a very unique juggling prop. It can be seen in the photo at the top of this page. It was used by Edith in the 1940s. Donated by Edith Sandor.
