Drawings Inside The Whale

When Casanova is in London, he visits a whale where men go inside and see projections of nude drawings. Does anyone know if those drawings were made for the movie or already existed?

This world is a comedy to those that think, a tragedy to those that feel.



The artist who made the magic lantern drawings from the circus whale scene was master draughtsman Roland Topor. Correct me if I'm wrong but most of them, or should I say all of them, already existed a priori to this Fellini masterpiece.
