Also, what is the true date, time and place of the photo (Plate 22) captioned 'the alleged Grand Duchesses... photographed in Poland, circa 1921'?
I'm a bit late to this discussion. I happened upon it because I was searching for the plate number of that photo for a citation. (Thanks for supplying it!)
What makes me chuckle everytime I read that claim of Richard's is the fact that the Grand Duchesses themselves pasted a copy of that photograph onto a postcard which they mailed from the Alexander Palace to the members of H.I.M. Convoy on June 25, 1917! It even appears at the back of E. E. Alferieff's book.
We intend to include it in our book, with an explanation.
