These are from approximately 1906 I have 15 of them I believe there might be 24 total The leather is dried out and there are some that are not in great shape and are falling apart This is quite common with these because they are so old, they dry out These are pocket size and fit like a size of an average hand There’s are really special and nice and if you can clean them up a little, they will look amazing on the bookshelf that are fun to look at
