19th c. watch fob made of mother-of-pearl carved in the shape of a book. I imagine it was supposed to be the bible and symbolized your faith, but there are no religious references here specifically, and to me it would symbolize my love of reading. It's just 5/8" tall but is hanging on a collaged length of gold fill chains (including a MOP link!) and terminates in a GF dog clip. Total length 2 3/8". c. 1880.
