These are two postcards that featured "Von" farming scenes.  I know very little about the area.  I believe it consisted of just a post office that serviced the nearby farm families.  The post office was in existences from 1871 to 1882.  Mail began to be delivered, by train, to Livermore in 1882.  This was probably why the post office was discontinued.  If anyone can supply more information about the area, please contact Karen.
