I don't know if this goes here or not, but I passed by a shop in Akihabara while I was there this past week called Liberty Akihabara and the third floor specialized in idol photos, mostly AKB and Sakamichi. I decided to go on a whim, and while browsing through the store, I happened to find the Nogizaka46 Artworks book in a case. I believe this is the book that was being pre-sold while the museum was up and running. I had no idea what the contents of the book were, but I didn't want to pass up on buying it, so I did. It's pretty much the museum in book form. Everything you saw in the museum is pretty much featured in this book. I don't remember what the asking price was when orders were being taken, but this is definitely worth the ¥3500 that I paid.
