nude people on the street?

Question

i need really quick an answer. I need the name of this photoartist who's making illegal pictures of nude people on the street, like red square Moscow, or New York Wall street etc
What is his name?

Answer 1

It is Spencer Tunick. But the photo shoots are not illegal. He gets permission now from the cities.

I posed for him in Cleveland, Ohio.

Answer 2

Yes, as previous answer says it is Spencer Tunnick. The pictures are certainly not illegal. Why do you suggest they are? He did one in Newcastle-upon-Tyne, England a year or so ago, with full cooperation from the authorities.
