This was something I was very pleasantly surprised to find at a local library sale. It's an official Ansel Adams exposure record log. It comes in a binder and has a short section covering the use of the log, the zone system and so forth, and has many pages for exposure records. The first two pages have a couple exposures recorded but the rest are totally blank. You can see in the last pic how many unused pages remain.
I don't really know what this is worth, but not only is it a cool collectable but it's a completely usable tool for the distinguished photographer.
Make me an offer, I don't really know what to ask for this.
