An advance copy of For Whom the Bell Tolls signed by Ernest Hemingway and including his handwritten corrections will be auctioned off in November by Swann Galleries. Ernest Hemingway literary memorabilia has always fared well financially in the bidding marketplace and this proof is expected to continue in that tradition.

The pre-sale estimate for the proof is $75,000 to $125,000. The final sale price, however, could be much higher since this is "the first signed advance proof copy of the novel ever to surface" according to the auctioneer. The proof is being offered by the descendants of Toby Otto Bruce, who was an employee and very close friend of Ernest Hemingway.
