Dude,
It has just about every Valkyrie imaginable. It includes the Series, DYRL, VFX 1 & 2, model covers, MZero, and a few other paintings. As far as technical info... it's pretty much an art book. Unless you know how to read the small print in Japanese. Thare are a few new pieces such as the cover (which is incredible) and a illustration of a WWII Bristish Spitfire, a gnarly unfolding pullout of Hikaru and his Valk in the hangar, and a new one of Roy in his flight suit.
