Years ago, I saw parts of this film on PBS in reference only during another show on mental illness and Sanatoriums. Today, I watch this on my PC and thought I should pass it on to you all in Abandoned Places. As all of us tend to "haunt" heh, these places taking photos, I thought perhaps you should see one as it was when in use. This is a masterpiece of cinéma vérité as stated in the Wikipedia entry.
If you know how to use FTP and wish to see this film contact me and we can set up a drop.
