I don't know that there are any from before 1916. U.S. lobby cards started in late 1915, and it seems like that gave the studios the idea to do pressbooks. I have seen single page press sheets from earlier movies, which have a scene from the movie and a synopsis, but I feel a real pressbook has to have at least one poster image.
Does this have any poster images? If not, and if it has nothing aimed at theater owners, it is likely more reasonably described as a program book. No matter what, it is still a cool historic item!
30 to 40 years ago someone found a large number of Italian lobby cards for this movie, and they turn up occasionally.
