Actually, I think they pretty much do.
Anyone who wants to see the Twain poem, at least, can follow this link to
the catalog:
http://search.sothebys.com/jsps/live/event/EventDetail.jsp?event_id=27467;
then click on "BROWSE CATALOG." The Twain items are nos. 15 and 16.
Oh, and by the way, I personally don't object to a touch of commercialism
here and there. And god knows neither did Twain!
