I'm reminded of the old Peterman catalogue, which affixed a famous name to most any object, but the following is for real--a typewriter used by Ernest Hemingway:
The typewriter, a Halda, was made in Sweden and is in excellent condition with the ribbon and keys intact. It is fully functional, in its original leather case with somewhat tattered transportation stickers from both the American Export Line and the French Line.Only $100,000. Are replacement ribbons available?
[Update: It's been sold.]
