I was in my History earlier today, and on my phone browsing this forum, reading a topic where the Grand Duchesses kept being mixed up when my teacher saw. He asked me how long I had been studying the Romanovs for, and I told him for so many years that 'I could identity the Grand Duchesses in a heartbeat'. When I said this, he turned my attention to a picture of some of the Romanovs he and the History department had been arguing about. He and two other teachers said that the girl in the photo was Olga, however the rest of the department said it was Maria. Taking a look, I told him that it was Olga (after squinting at the photo) because of the shape of her head but from far away (as the picture had been shrunk) it did look like Maria until you zoomed in.
So I'm wondering how many Romanov photos you have seen that at first glance looked like Olga/Maria then either being told or looking closely at the photo that was the other?
Here's the photo if you are wondering (Alexei, Nicholas, Olga and Tatiana):
