English: A V Alexander

The sketch may have been based on a strikingly similar wartime photograph taken at The Admiralty in London by Yousuf Karsh (usually known as "Karsh of Ottawa"). The pose and some details (e.g., the pattern of the tie worn by A V Alexander) are identical. The photograph appears facing page 10 in the photographer's published book "Faces of Destiny", sub-title "Portraits by Karsh" published 1947 simultaneously in Great Britain by George G Harrap & Co Ltd., London, etc., and in the United States by Ziff-Davis Publishing Company, Chicago and New York. The foreword to the book by Yousuf Karsh is dated June 1946. His detailed description of taking the photographic portrait is found on page 10.
