Amazing. I'd seen this photograph before and fell in love with it immediately. I'm pretty sure the model however is Julia Jackson (not Virginia Woolf, who had a more crooked nose), who was the niece of Virginia Woolf, and the photo is by Julia M Cameron. Please let me know if you can verify this information.
Many thanks for your comments John : )Sorry for bad english : I'm French ...)You're right, this is certainly Julia Jackson : )But in fact, Julia Jackson was the mother of Virginia Woolf and the niece of Julia Margaret Cameron.
