Cormac McCarthy is auctioning off his typewriter. Proceeds will benefit the Santa Fe Institute.
A quote from the authentication letter that he wrote:
“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.”
