I'm not seeing the original photo and your's looks to be under glass, but I am not sure the number is original to the photo. There is no shadow from the marker light and for hand painted numbers, they came pretty close to the window sill. It is more reminiscent of a bad photoshop job with out rescaling the numbers. I'm not sure you will find any specific information about the photo (at least with that number). As others have said, there are other "versions" of the photo around. Beware of "flea market" vendors at car events.
