"The Ordeal of Chief Parker" by Jerry Sigel and Plastino
"The Rock n' Roll Riddle of Smallville" by Cary Bates, Brown, and Murphy Anderson
...and if that wasn't enough Smallville-ania for you, there's a text page by ENB about some of the other denizens of the town! Man, when's Carl "Moosie" Draper gonna show up on the TV show?
And is it me, or is the Superboy on the cover(by Andru and Giordano, 'natch) really, really bulked up?
