I am fairly certain that this is the mannequin that was photographed with Joe et al, at last year's Cannes party, in May 2011. From the photographs at the time, this seemed to be about life-sized.
Last seen in the 'Joe launches biographical film at Cannes' thread, pictured in post 92.
There seems to be no description, beyond the title.
There are more, close-up photos on ebay
PS the artist is Jean Baptiste Seckler, GREVIN artist museum of Paris
