No Country for Old Typewriters – A Well-Used One Heads to Auction – NYTimes.com.

Christie’s, which plans to auction the machine on Friday, estimated that it would fetch between $15,000 and $20,000. Mr. McCarthy wrote an authentication letter — typed on the Olivetti, of course — that states:

“It has never been serviced or cleaned other than blowing out the dust with a service station hose. … I have typed on this typewriter every book I have written including three not published. Including all drafts and correspondence I would put this at about five million words over a period of 50 years.”
