Sorry, but the fact that it has this many pages missing, means that it is like having a copy that a child has crayoned all over, or has been very badly water damaged.
It is not worth anything as far as I am concerned, buyer beware
That's an entire gathering missing ("gathering I" as labeled in the facsimile edition). From the photo, it does not look like it was removed, it appears to my eye that it was never there in the first place - thus a binding error rather than a damaged copy. Doesn't change the fact that this is not really a collectible copy in my mind either.
I do expect it will get bids - will be curious to see if there is a minimum and if it is met.
