These hard to find items were once a novelty for those that like a little titillation. The figure moves with the aid of the tiny crank at the bottom. When turned the figure gyrates in a surprisingly realistic way. I have four different ones to choose from or if I were you I'd get the collection. They are:
Madame Le Strippe
Behind the 8-ball (blonde and brunette)
The backs have stunning graphics --they show wear from storage but have been rarely used. Sold individually.
