I understand why (historically), but it is still one of those things that cannot be unseen once you see them - there are no women in those paintings/photos. It really boggles the mind of a modern human.
>> there are no women in those paintings/photos. Except the last one, the one from 1995. Progress happened. I"m glad to see that the first woman to be depicted is actually sitting at the table. I'd be unhappy if the one woman in the article was servant or mistress to one of the men. This woman is clearly a world leaders, although I cannot figure out who she is. (Is the woman leaning over the table Hillary Clinton?)
I think the woman in green leaning over the table is some sort of aide rather than a person of power in her own right. See e.g. the picture here https://www.aljazeera.com/news/2020/11/20/dayton-25-years where she's apparently sorting out a document for the president of Bosnia while others to her left and right are doing likewise for the presidents of Serbia and Croatia.
