Gah…..what happened? Plating must have went far south during the restoration, poor thing. I remember seeing a thread here a while ago about the story behind the plating of the hero idol and what it went through. Did this happen during the Hata exhibit/book period?
Also, mention of the book drove me nuts so I drove over to my place, disinfected every inch and the book and took some higher quality photos of the idol. Its only one image of the idol that's featured, which is used again on the back cover. Sure enough, there's small bubble dimples along the chin and pooling in some areas indicative of spray paint. Also I was just curious if a stray idol image was somewhere else in the book, no dice. Though side plot: The book heavily features the grail diary for anyone doing their own grail replicas.
