Point of order for clarity only;
The binding in the ebay pictures is not a spiral binding, it's a comb binding.
Are you guys saying that the binding in the photos is not how Karl released the volume, or is how Karl released the volume?
A spiral binding gets wound into the spine of the book (and is sometimes called a "wire" binding even though they do make plastic "spirals"), the comb binding is a piece of plastic that gets "opened up", and the slots in the books spine get placed over the comb binding.
I suspect you're all actually saying that you have a "comb" binding, but for these high bidding Fulves collectors, the clarity might help.
