This was reproduced in the Illustrated London News.  This is of Princess Alice, Countess of Athlone, and the reproduction is from the Illustrated London News issue that marked the Silver Anniversary of her wedding to Prince Alexander of Teck, which took place February 10, 1904, so I assume it dates from 1929.  Alice was born the daughter of Prince Leopold, Duke of Albany (son of Queen Victoria; d. 1884) and his wife (nee Princess Helen of Waldeck-Pyrmont).   Princess Alice married Prince Alexander in 1904, and they had three children. During World War I, when German names and titles were unpopular in England, the title Prince of Teck changed to Earl of Athlone.
