I don't know. The only current bag I know of where the strap attaches flat to the front of the body of the bag like that is the Hippie, but that one clearly shows the buckle, which would be on the front, but no flap. Plus, it is a different color.
When the Hippie wasn't available yet or listed online, I called a bigger store and directed them to that photo and they were able to tell me what it was. Apparently they were able to get a style number on the Hippie, even when my computer would not. Have you tried calling a store, directing them to the photo at the top of the page when you go to Legacy and then to Handbags and asking them what it is?
That doesn't appear to be a white Legacy Hippie bag, either, now that I look at it (the one in the middle, right behind the whiskey). The strap appears different, as does the front pocket... Perhaps both of the bags behind the whiskey Hippie are vintage or props of some kind?
