I've read manga by Takamichi before, and his color work is really exceptional. If you want to get a good large sized book with prints of Takamichi's magazine covers, this book is the one for you. Paper quality and print quality are good. The end parts also contain interviews and artwork creation process, although these parts are in japanese. Great art book for fans!
Fair warning, the covers are for Comic Lo, so if you can't look past that this may not be a book you want to get. In that case, I recommend the manga as it is unaffiliated. For those unaffected by that stuff, go for it, the price is good for how big the book is, too!
