Yes and No. Because Token Kantei Dokuhon was written for Japanese beginners. As non-Japanese you need some basics and you have to read it again and again. So Yes, it is for the advanced collector.
What I miss are essentials in collecting when it comes to books. And I think that the english Token Bijutsu belong in every good collection.
Koto Taikan, Shinto Taikan, ShinShito Taikan, Soshu Den Meisaku Shu, Meihin Katanaezu Shusei, Nihonto Shubi is up to you. Sano Art Museum books, books from the NBTHK, whatever...
And never forget Dunning-Kruger.
