Hi, I've had the attached photo for a very long time. I think she may be from my Grandmother's side, she was born in 1891, although it is not her. I wondered if anyone could have a go at dating it? The reverse is a post card. No restoration required as the original is in good condition. Thanks in advance for any suggestions. I have some more photos but will post them individually. I'm not sure if this is the correct procedure, so apologies if not. Thank you.
