Hi all:
I'm looking for a couple good public domain photos of Mark Twain to use on a
World Wide Web Page (Cap'n Mark Wheeler's Virtual Riverboat).
http://www.acy.digex.net/~capnmark/home.html

Any suggestions on sources (free) would be appreciated. Especially
interested
in any photo in a steamboat context if such exists.

Thanks in advance.
