The site claims to represent the estate of Mark Twain and controls all use of his likeness, etc. for business purposes. http://www.cmgww.com/historic/twain/index.php Given that almost all of his work is in public domain, what do they actually control. Are they, in fact, just posers. The site is not particularly impressive as web sites go. I am curious because I've developed a audio/video book of "A Connecticut Yankee in King Arthur's Court" on a 32GB flash drive that I'm hoping to market. It contains an icon of a rather well worn photo of Twain. As far as I know, all my materials are public domain
