It is hard to tell, since OTMA were born earlier, correct, so they must have taken more photos. But ehh, really? It is hard question, and even there is harder answer. Well, if we count photos of each of the Grand Duchess, it 'could be possible' that they have more photos than their brother alltogether. We would know, if we counted all the photos, and then compare the results. Unfortunately, the real number of their formal photos is unknown.
