Looking for Peanuts: USA Today looks forward to Fantagraphics Books' The Complete Peanuts: 1950 to 1952:

"Even die-hard Peanuts fans may be surprised by the first book. Shermy, who eventually faded into obscurity, is the prime character. Charlie Brown appears in early strips. But like most of the beloved characters, he possesses little of his later existential angst. Chief antagonist Lucy is a toddler, not the mean-spirited, football-grabbing nemesis she evolved into. And Snoopy is just a small, affectionate puppy without his later fantasy life.

"'The characters really hadn't found (their) voices,' Fantagraphics editor Eric Reynolds says."
