I was browsing an art magazine and found these photos by Callie Shell.  She started taking pics of Obama when he was an almost-nobody during the Kerry run.   Just keep clicking “more images” at the bottom of the page.

The one of the little boys with their upturned faces just kills me.  And I love the one of him and Michelle on the bus.  And the one of him in the stairwell waiting to do his third speech of he day.
