Doug, it's difficult to do much of a search without the title and
authors name..is there a title there that I'm missing?
You could be dealing with a rare title, and while condition
is always a critical factor in a books value, the issues I see
with your book can be corrected by a professional.
Here is a link to the Booksellers Assn. in Texas. It would
be well worth your time to have that volume looked at, and were
it me I would call a few of the stores local to you and see if they
have a person knowledgeable on books from that era.

FWIW, I would be sure to keep it dry, and out of the sunlight.
Do not seal it in a plastic bag, as humidity will develop inside
and cause damage.
