I am preparing a program on an autograph book I found in a local historical society museum containing 236 signatures of Representatives to the 48th Congress back in 1884.  I am unable to identify two of the signatures, which I will attempt to attach hereto.  I have compared them with a list of all of the members of that Congress, with no success.  If someone could identify them, or point me in some right direction, I'd be grateful.

Are there any benchmark sales of such autograph books that would give an idea of what such a book is worth?
