My god! --that's as many LR first editions, as I have 1977 copies of The Silmarillion...

Well, not quite.

Here is a link to a german article about the museum.

Quite impressive what he has collected so far in a short time:
Over 600 original paintings from over 100 artists
Every british impression of the Hobbit up to 1999
Signed first impression of the Hobbit and LotR (with a dedication in Quenya, to Elaine Griffiths „Elainen tárin Periondion ar meldenya anyáran.)
Signed first US edition LotR
Signed first Italian edition LotR
etc etc
around 3000 books all in all

Beren:
Since you are mentioned in the article and on the official website as an Library Consultant & Webmaster, have you already been at the museum and seen his collection?

Every H impression, to 1999?; I don't think so --I'm sure there are a few missing, from that H photo.
