June 28, 1952: All is vanity

Schroeder has said a word in English before, but it's rare for him. Notice that Schulz considered that Schroeder's musical talent was well-known enough by now that he didn't have to establish it.

February 14, 1951: Valentine's Day

Another turnabout strip, another chase, and more of CB's playful insulting of Patty's looks.  The punchline, "It's risky, but I get my laughs!" is almost the same as a prior chase strip, I notice.

At first, Peanuts didn't take much notice of holidays. My theory is that, as a cartoonist's run continues, their initial stockpile of ideas and energy becomes depleted as the enormity of the task settles in, and they start having to riff on whatever comes to mind. That is the true test for a published cartoonist, not how great the strip is at first, but can they keep it up?
