Brown leather belt or teaching longe, used in the acrobatic training of Jeanne, Gaston and Georges Mongador, late 19th century.

Pierre Chambeyron, a 19th century French circus manager and equestrian, married a high-wire artiste, Mathilde, and toured with the Circus Clark. Their children, Jeanne, Gaston and Georges, formed an acrobatic dance act called the Trio de la Rambla, and from about 1900 Georges concentrated on juggling, forming The Mongadors in about 1900.

In the early 20th century The Mongadors and the Trio de la Rambla were very successful troupes, topping the bill everywhere. The Mongadors were always ahead of their time and from their early days appearing with the circus, moved into variety. At one point they lived in London and toured extensively in the UK and abroad. From about 1950 until the 1970s the troupe appeared as Ninette Mongador & Co. and comprised Georges and his wife Anne Mongador with their daughter Ninette (Antoinette), the donor of this object.
