Can anyone provide contact information for this aging surrealist?

Dear nat1973,

The Google Answers guidelines prohibit the Researchers from publishing
contact information for living individuals in their answers.

However, I am allowed to direct you a resource that will provide you
the information you are searching. Leonora Carrington (whose name is
connected with "Weisz", since that was her husband's name) is listed
in the official Mexican telephone directory. The address listed refers
to Mexico City (Ciudad de Mexico), where Mrs. Carrington is living and
working today, so it is most likely also the address of her studio.
Please follow this link to the phone directory:

Hope this helps!
