Just read this book a few minutes ago. I couldn't put the comic down before finishing it.
It has been a long time since I've been moved by a comic, maybe the last time was 20 years ago, after I've read a comic by French author Tardi "C'était la guerre des tranchées" ("It was the trenches war"- yeah, i'm French, and 40 years old.)
Magneto Testament has an hard setting ( The Holocaust),and besides the comic there are a few pages about this artist, unable to get her paintings back from the museum of Aushwitz:Dina Babbitt
It's a must read book, IMO, for historical reasons and to never forget.
