George A. Birmingham was the pseudonym of James Owen Hannay (1865-1950) an Irish priest and novelist. This novel was first published in 1911 by Thomas Nelson and Sons, as far I can ascertain.
The dust jacket was commissioned in a letter from Edwin Chater Jack dated 8th June 1917, sent to Blampied at 2 Winchester Villas, St Helier, Jersey:
We are sending you herewith two volumes, Clementina and The Inviolable Sanctuary. We are also sending you a wrapper showing you the style of design wanted. All that is required is the panel, no lettering, and we would like to have these panels bold and decorative in colour. In case of The Inviolable Sanctuary how would it do to give us a boat with a fine blue sky behind it, but we can safely leave the selection of subjects to you.
I haven't seen the jacket of this book. I have a copy of the book without a jacket which has an inscription dated December 1917, so it's probably the Blampied edition. There is no copy of this edition listed in Jisc.
