I love the evolution of the document icon! You can see what the designer(s) thought and the different reasons why each one might have been rejected and replaced in turn. I've put together a few "evolution" graphics like this for clients to show how we've iterated to create logos. I would love to see the designers' processes for other ubiquitous things like this.
