For the past six years, illustrator Larry Roibal has been sketching on the pages of his morning newspaper — drawing portraits of politicians, world leaders, entertainers, sports figures and other newsworthy individuals directly on sections of newspaper articles about them, and then publishing the sketches to his blog.
Roibal has collected all 1550 of his newspaper sketches to date, and published them in a Zoomable interface.
