Lightning Express broadside - Is this an original?

From: "Paul Wagner" paul_wagner@hotmail.com

I got this [Lightning Express!] broadside from an oldtimer in San Diego who had lots of old California stuff. I thought at the time that it must be a reproduction, but after doing some research, I'm not so sure.

Has this ever been reproduced to your knowledge? Could it be an original, from 1876?

It measures 11" x 17" and the paper is rather stiff. ...
