Yes, plus that is one of the most familiar poses of MA (with the hand up to her chin). It appears in various forms everywhere. I wonder if that's because she was photographed less and less as her health worsened? Believe me, there are quite a few of the QV ones and they are SO FAKE! You really don't have to be an expert on lighting or anything to tell.

It must've been a cheap way to distribute multiple images--I have some postcard (not CDV or cabinet card) images as well from the period of Edward VII so it wasn't just because of limitations of photography back in the 'old days'. I enjoy them though--it's fun to match the people with the settings they were originally taken in!
