I like it a lot. It does raise the question about the "universality" of photos containing a recognisable person: in Europe it would be illegal to exhibit that photo without the permission of the woman, but aside from that, how does someone feel about hanging a photo which contains a recognisable, non-famous stranger?
To me, it feels like a sort of intimacy to have some's image on my wall... and I'd quite expect someone to ask "Who is that?"
There is sliding scale in my perception: to illustrate, two photos taken recently in Barcelona. The first is possibly legal, since I think Spanish legislation allows photos of "crowds" defined as at least 6 people: I could imagine hanging it because the subject is "bunch of people in a shoe shop". The second I'd be less comfortable with, because it could be "scene from a tapas bar", but it could also be seen as a portrait of the guy (and maybe of the woman behind him)...
Both would be clearly illegal in France. I have another photo, a head-shot portrait taken on the street, which I don't even feel comfortable posting here although it would certainly be within Gary Winogrand's comfort range...
