AAUGH: The First Peanuts Strip
Peanuts launched with just four panels, and the AAUGH Blogger, Peanuts specialist Nat Gertler, spends fourteen minutes poring over those panels. Oh, well, including asides about popcorn.
To follow along, you can see the strip on the GoComics site. Alas, that version is colorized, so it’s not the pure experience. A smaller but appropriately black-and-white version can be found on the Wikipedia page about Peanuts. Or you could simply open up your copy of the first volume of The Complete Peanuts to the first strip. (If you don’t have a copy, you should. I invite you to go buy one!)
