California Central Rail Road, Engineering Department, neatly-struck on cover franked with 1857 10c. Green, tied by Folsom City Cal c.d.s. (4 Aug), to Greenfield, Massachusetts, sent by Theodore Judah, Surveyor and Engineer of the California Central Railroad, to his wife, a choice example of this rare railway cancellation; throughout the 1850s, Judah was known as "Crazy Judah" for his desire to build a railroad through and over the Sierra Nevada mountains, considered by many at the time to be impossible.
