Crikey! There'll be 974 copies of the book, as agreed in the contract. The books will be numbered 1 through 974. basically, I guess we'll be saying this to repeat customers: "You're buying your number XXX, Now, which book would you like around it?" The books themselves will have all the same pieces albeit in slightly different places.
Thus they'll be like this:
EDWARDS EDITION
* Buzzard slipcase
* Pie dust jacket
* camper van endpaper #1
* Oldsmobile endpaper #2
MILLER EDITION
* Oldsmobile slipcase
* camper van dust-jacket
* pie endpaper #1
* buzzard endpaper #
Aside from those, the books will be identical.
