Hemingway's favorite machine of choice was the Royal portable typewriter. Here is a photograph of his writing desk and Royal portable in his home in Key West, Florida. To the left, you can see a closeup of this classic machine, accompanied by some of the descendants of his 50+ cats he owned.

At this desk he wrote many of his classic novels including - "Death in the Afternoon", "Green Hills of Africa", "To Have and Have Not", "The Snows of Kilimanjaro", "For Whom the Bell Tolls", "The Short Happy Life of Francis Mancomber", among others.
