Mirror, Mirror on the Wall...Who's the Fairest of Them All?

This photo reminds me of photos they used to take of kids in the 80's. I don't know what they are called, but they show two photos of the same kid. One is a regular photo of the kid sitting, but then there's another photo that's smaller and higher up that looks sort of like a shadow or a reflection. If someone knows what I'm talking about, help me explain. Whatever the case, this oozes cheesiness, which isn't very common for a photo from this era. I don't even know if people back then really had a sense of something being cheesy. Maybe they had a sense of tackiness in furniture, decor, or behavior? I don't know...
