Family puzzle

It's an interesting product: I've never before seen a puzzle in which the pieces are laid on top of one another like this; I suppose that would also help with the skills required for plotting things in three dimensions. The five layers depict a growing boy and girl from babyhood to old age, providing a nice representation of how each generation comes from the one before it.
