I'm looking for a poster (or even better a replica) of Kathe Kollwitz's "Tower of Mothers." I notice that you have a really high quality photo of it up. Is this from a book, or a poster? If so, what's the title/where'd you get it? I'd really appreciate any help.
Books that may have the image include Prints and Drawings of Kathe Kollwitz (Kathe Kollwitz and Carl Zigrosser) and Kathe Kollwitz (Elizabeth Prelinger, Alessandra Comini and Hildegard Bachert)
