ELI5: How does Banksy publish books anonymously?

Banksy is a very well known figure for graffiti art and his protest art, he has published books and had exhibitions for his works. How then does he remain anonymous? Is it as simple as signing a non-disclosure agreement with his partners or is it more complex?

Two parts discretion, one part NDA.  You work with the same people, who are all financially invested in keeping the working relationship going.  Even if there was no NDA, they'd still want to keep on good terms so they get to publish the next book.
