Letter Book number one is half the size as Letter book number two. The pictures have a spiral going right though them. Also no thick cardboard backing to help keep it from flopping around. I was told to keep the book original style it would cost $160 which doesn't make sense because it's all the same except the pictures are cut in half and there's a plastic spiral instead of metal. And no cardboard backing. So basically a piece of cardboard and metal spiral in the cost of cutting pictures of a half would be $80 for them...
