In the Wiki bio of Tatiana its reported that A group of officers aboard the imperial yacht gave her older sister Olga a portrait of Michelangelo's nude David, cut out from a newspaper, as a present for her name day on 11 July 1911. "Olga laughed at it long and hard," the indignant fourteen-year-old Tatiana wrote to her aunt Grand Duchess Olga Alexandrovna of Russia. "And not one of the officers wishes to confess that he has done it. Such swine, aren't they?
Then I have read elsewhere it was a photo of the Prince of Wales, the future Duck of Windsor, whom the family called " David"
I'm leaning towards the latter explanation as the far more likely one to be correct! It seems more likely the officers would flirt like mad and then , as a joke, offer a likely suitor. Would a paper at that time even publish the nude David? I will say in 1911 it was far more likely to see the rock star Prince of Wales in the newspapers than Michelangelo's statue And it also seems to me Tatiana was amused too... the " swine" part being no one would admit to it. It was written to "sweetheart Aunt" Olga Alexandrovna, who would enjoy such a joke and I believe understand it to mean David, the Prince of Wales.
Sorry if this was thrashed out before. It's in Wiki and therefore of import.....and there is a saying : " a falsehood will run around the world before the truth has time to put on its shoes"
