I don't think this is real, even though you never know. That's the fun of the mystery, right? (you all nod your heads as you obviously can tell it's fake). This looks like it used the Lord of the Rings effect, as I call it. That's where you play with how close or far your subjects are to make them look like they are on the same plane even though they're not. That's how the hobbits looked so small in the Lord of the Rings. Now imagine a rainbow flying by with the words "the more you know."
It's possible that this could be real though. Who knows what the famine years did to people back then. The small fry could really be that size. His face is squished, so he might be one of those weird squish-faced small guys. You know the ones I'm talking about.
