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 (ghostoid?) shapes representing the signers.
Colorado College students reading 18th century literature were in Special Collections recently, and at one point we were talking about identifying people by their handwriting. I ran and got The Ghosts of My Friends since it suggests that a person's handwriting is that person in a profound way.
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. Maybe there's a copy in a library near you! Or you could purchase a copy from abebooks.com for $30-500 (the most expensive one for sale today includes the "ghost" of actress Sarah Bernhardt).
