Search of newspapers.com, newspaperarchive.com, newsvault, newsbank, the Times, The Guardian, The Economist, The Picture Post, and The Illustrated London News without finding any photo that confirms who the author of the image is.
If Carl Vandyk (1851-1931) or his son Herbert (1879-1943) are Vandyk then 70 years have lapsed since they died. Unable to identify who Barratt might be. According to this sitearchive copy at the Wayback Machine photographers with the surname working in the UK between 1840 and 1940 included A. Barratt, George A. Barratt, John Barratt, Lucy Germeuil Bonnaud-Barratt, Peter Barratt, Barratt & Stanley, Barratt’s Photo Press Ltd, Boswell & Barratt, and Hobbs & Barratt. There is insufficient information given in the newspaper article to identify which of these the photographer might have been. All photographs by Joseph John Elliott (1835–1903) & Clarence Edmund Fry (1840–1897) have clearly exceeded 70 years since their deaths. Same with Alice Hughes (1857-1939) and James Lafayette (1853-1923). If her photo was made by Topical Press Agency, it did not dissolve until 1957, so that might be problematic, but we have no evidence that they made the image. Search reveals nothing at all that might indicate who or what Lassano was or when it existed. Likewise, nothing at all for Hoppe and Russell.

or
it was first published outside the United States (and not published in the U.S. within 30 days) and
it was first published before 1978 without complying with U.S. copyright formalities or after 1978 without copyright notice and
it was in the public domain in its home country on the URAA date ( January 1, 1996 for most countries).
