For at least some more information, here is a link to the auction where it was sold, in case you haven't seen it:

It does not look like it is a cdv-it is too big according to the Heritage website.
Finally, and most importantly: it is a great photo! California baseball memorabilia from the 19th century is pretty rare, which I bet you already know.
Best,
