Hardly a fair comparison. I have a lot of photos of Queen Mary from magazines of the day visiting all sorts of hospitals, orphanages and other charities and in most she's smiling and interacting with the people. It's really just buying into the old stereotypes. I know I bang this drum a lot, but people should really try to get their hands on magazines from the period of about 1896 (when photos became more common than illustrations) through the 1930s--in English, German, Italian, whatever. The provide treasure troves of rare and candid photos. Many libraries even have bound up magazines from this period--and there are dozens of titles to choose from if you search.
BTW, you can find the image of Queen Alexandra in either the Graphic or the Sketch magazine. Can't remember which one but the issue was for sale not too long ago.
