I bought the hardback edition of this and it arrived today.
It is absolutely fantastic, as you would expect from a HPLHS production.
I have some of the other monographs, so thought I knew what I was getting myself into. How wrong I was. This is huge. And heavy. It is crammed with so much detail that pouring over it immediately immerses you in the phantasmagorical world and mythos that the HPLS has done so well at bringing to life through their projects and ephemera.
The quality is excellent, which is standard for HPLS, and the binding is solid. The pages are wonderfully illustrated and due to the large size, very detailed.
One could definitely envisage pouring over this tome by candlelight with Professor Armitage.
