I've just posted it as a fairly large PDF in the "Other Books" section - pretty much as it was published in 1936, but with a cover reconstructed from the 1931 first edition. It contains no material but Gill's original text, so hopefully it is properly in the public domain.
It is, I think, a reasonably good scan too.
The only way in which it fails to reproduce Gill's original is that he clearly designed the book so that (in parts, anyway) facing pages needed to be seen simultaneously: an example is his re-working of a John Bull poster with the words "A DEMON who lives on the DEAD". But that's a minor issue.
