No, I can't really see a scar in that photo either. Yeah, in the 1914 formals, she seems to have quite a short fringe - suggesting the scar is higher up.
Maria~fan: yeah, I think so too, it seems something that the LP would do.
Ohh, just had a thought:
This photo from 1917 with all their heads shaved - the still appears to be no scar on Nastya's head (well to me at lease!)

your picture was a bit bright for me to see
so i got
this one, and yet still no scar.
