I feel that the bottom half of the picture is hand drawn. I mean, I can clearly see that it is. But the top half, seems like an actual photo. I think my opinion is pretty close to yours. What year is this? What is being omitted at the street level? I can only assume that something is being hidden. And with that opinion, I can only assume that whatever it is that is being hidden would clearly prove that "the timeline is false, the date is false" and we would immediately call for an OOPA!
