How can I get a whole stamp album valued?

I have a very, very old stamp album in excellent condition. The oldest stamp is dated 1904 and there are lots of stamps from world over, many of which during the first and second world wars.

The stamp album itself still has the original world map that went with it.

I know there's not much you can tell me with such little detail, but I was wondering if you could point me in the right direction with regards to getting it valued.
