French lucite mannequin designed by Rene Herbst for the Siegel mannequin company and supplied to the English shop fittings company of Yugin and Sons. I have two of this same mannequin both with lucite boobs. Herbst made many different styles of these mannequins, some were metal framed with metal framed and some lucite and some were wooden or a mixture of different materials.
This one is a floor standing one and can extend to approx. 6 feet (183cm) tall or as little as 56 inches (143cm) and 15.5 inches wide to the shoulders (40cm).
Condition is very good. They are highly sought after and some command very high prices.
