May 11, 1953: Snoopy and the realistic bird

This is only the second bird ever seen in the strip; the first was seen early on, and actually looked more like Schulz's adult bird design (which to clarify _doesn't_ look similar to Woodstock) than this one.

This is only the third non-Snoopy animal seen in the strip. (The second was a generic dog who chased a car.) The worm would be the fourth, I guess.

October 23, 1951: Finding only half a worm

Another Calvinesque strip, right down to Charlie Brown's angular smile in the last frame. I can picture Calvin doing this to Susie very clearly.

The outline of the tree in the third frame seems rather artsy for Peanuts. It's a nice effect though.
