In the category of Books Every Fan of Comic Art Must Own comes It's Only a Game, a collection of the "other" comic strip by Charles M. Schulz, the one he rarely mentioned in interviews because it was not successful. Between '57 and '59, with Peanuts not yet the hit it would soon become, Schulz also produced a sports-oriented three-times-a-week-plus-Sunday comic panel, working with cartoonist Jim Sasseville. (Sasseville was then also helping Schulz produce material for Peanuts comic books published by Dell.) The strip, which covered every sport Schulz and Sasseville could think of, started with a modest list of subscribing newspapers. A year later, it still had the same modest list…and with Peanuts requiring more and more of his time, Schulz decided to pull the plug on It's Only a Game. All in all, it lasted 63 weeks.
Still, the resultant feature is a nice reminder that Charlie Brown's maker was a multi-faceted cartoonist, not just a guy with one idea, and we have Nat Gertler to thank for putting them all into this inexpensive (a little over ten bucks) volume. Here's a link to order your copy from Amazon. I suggest you do.
