You can find these test files in several place on the internet, one of
http://www.itu.int/itudoc/itu-t/com16/tiff-fx/t-cases/index.html. As far
as I am aware there is only one revision of these files.
For some reason, this page did not offer download links to the files. I was able to retrieve all but one using 'wget' via simply-guessed download URLs based on the file names.
