Or perhaps Mr Hergy is a pseudonym for Pam Ayres?
I always thought that there must be more to her than meets the eye...!
I think that this is basically a fancy coffee-table guide to the Museum; Michel Daubert's name apears to be attached to books on other institutions, so it would seem to follow.
It's hard to see, given the
Complete Companion and
Chronologies, that there can be much left to be given unprecedented access to that will be "new" to the dedicated student, hence my feeling it's meant to be the definitive guide to the Museum's collection itself.
