In Britain in the 1930s, Laura Henderson began presenting nude shows at the Windmill Theatre in London. At that time, British law prohibited naked girls from moving. To avoid the prohibition, the models appeared in stationary "tableaux vivants". The Windmill girls also toured other London and provincial theatres, sometimes using ingenious devices such as rotating ropes to move their bodies round, though strictly speaking, staying within the letter of the law by not moving of their own volition. Another example of ways that the shows stayed within the law was the fan dance, in which a naked dancer's body was concealed by her fans and those of her attendants, until the end of her act in when she posed naked for a brief interval whilst standing still.
