I'm glad you agree! I wasn't sure if I was seeing things, because I didn't know he appeared in the strip this late. He's no longer taller than Charlie Brown, and yes, his hair has changed a bit, but I do think it's him.

I wonder why Charlie Brown is the only character who is always referred to by his full name? It's been like that since the beginning. The exceptions to this rule are Peppermint Patty ("Chuck") and Marcie ("Charles"). No one ever, ever calls him "Charlie."

Speaking of such things... do you know if it was ever established whether "Schroeder" is his surname or his given name? I tend to assume the former.
