Camy,

There are other laws that govern how someone's name and likeness
can be used. Both trademark law and something I usually see referred
to as "rights of publicity" might come into play. In the mid-1990s there
was a legal case that got a lot of coverage when a city in Nevada was
sued for using Mark Twain's name and likeness in an ad campaign to
boost tourism. Hal Holbrook has said that he pays the Mark Twain
Foundation for his use of Mark Twain's name and image.

This is the official web site for Twain created by the company that
handles those rights for the Mark Twain Foundation:

There is an article there saying that Twain's play "Is He Dead?" will open
on Broadway in October.
