The Ghosts of My Friends is an autograph book with a twist. Published in the early 20th century, it’s a near-blank book meant to be used for sideways signatures to be turned into “ghosts,” that is, humanoid (or ghostoid) shapes representing the signers.

The “ghosts” pictured here were made in 1916 from the signatures of Polly McKeehan and Geo. B. McDonald.

There are about 40 copies of The Ghosts of My Friends in U.S. libraries. Each one, of course, would contain different ghosts. We brought our copy out recently during a class discussion about identifying people from their handwriting. This book takes that idea a step further, suggesting that a person’s handwriting is that person in a profound way.
