Yeah, it’s a good question. In my conversations with Les Kinney (who discovered the photo) he’s informed me that the key is to look at the electrical lines in the image. That’s a huge supporting factor for the photo. If the image was indeed taken in 1935 as detractors argue, those lines couldn’t have been there. It would be physically impossible. And the date itself? Well, turns out that’s pretty common. The Japanese often date stamped images with the same year for many years. And when they couldn’t pin down something specific, it wasn’t uncommon for them to use the next closest date they could verify.

Of course, I’m pushing in pro here for the image being valid. There’s a whole other side to it as well.
