I was probably the biggest "Peanuts" fan when I was a kid. Hell, I even collect all the books now. I simply can't say that I did not love this. It is kind of funny how he's so sad. He has a full head of hair! You really did get the style of the comic down perfectly.
I drew these characters all the time when I was a kid. They were just so easy to draw! You of course represented them (or I guess just him) perfectly in this. This must have been him as a teenager. The color is beautiful and lush. Charlie Brown now and forever!
