Want to see the original drawings for the Red-Blue Chair? Or find a little-known fact about one of designs of Gerrit Rietveld that normally would require examination of an original or a long conversation with someone from Christies? And then, maybe, actually build the piece yourself? This is the book to get. It's not enclyclopedic, though, so make sure what you are interested in is present in the 50-or-so works present. Also has some terrific old photographs of the workshop, original installations, lines, and advertising.
