London: Cassell and Company, Limited, 1931.
Hard Cover. First Edition. Signed. With a warm inscription from Mackenzie to Ralph Pinker in the year of publication.~Pinker was one of the sons of James B. Pinker, founder of the Pinker Publishing Company in London. Ralph Pinker was later arrested and imprisoned for embezzlement, and the Pinker Publishing Company was no more. An interesting association.
Very Good binding / no dust jacket.
