You place a picture or a bank note in one side and then you show it to the other person and by "magic" the photo changes to the other side. Recently I found out my little nieces have one of those, it looks like this:

I first saw such a thing under the name of a reversable wallet.

I've also had a toy like that though with more panels and it was called a jacobs ladder.
