The wormwood society version was scanned from a reproduction owned by an absinthe aficionado (then) out of Atlanta.
The version reprinted by David Nathan-Maister, was "directly scanned using state-of-the-art equipment from the original copy of the book in the
Virtual Museum, and so all illustrations are complete and crystal clear."
If anyone is seeking close-up scans of any of the fold-outs or plates from an original, just let me know.
