I know it's from the side, but doesn't she sort of look like Wendy Darling?
(image borrowed from Disney Wiki)It's probably nothing really, but I created my own Disney theory that Darling is Wendy Darling, before her hubby goes off to war. I don't even think Lady and Tramp happened in London but as I said, I was likely addled so early in the morning, but when I saw this on my calendar and was looking at her profile I thought of Wendy. And they do have a name in common! Perhaps Jim Dear calls her that as a nickname! LOL!
But it was just something that I thought was interesting, though it likely holds no factual value as far as Disney theories go! LOL!
