Great book, got it from Amazon, which is probably the most affordable, as far as I've researched. Due to its design I suppose, some ink from the pages may come off so be careful with this book!
If you like the macabre, especially Goth culture, this book is for you. It covers a good breadth of her work. Although missing are captions and more coverage of individual projects would be better. There is another book on Sigismondi you should look for as well. I believe it is self-titled under the artist's name.
She also does sculpture, which is missing in this book as well.
Pictures from her seminal works, including music videos of David Bowie, Marilyn Manson, etc and even pictures from her anti-drug TV ad and artwork for her poster for the Toronto Film Festival are all in this book. She is definitely an important artist in the Music Video field. Get this book!
