April 22, 1954: So, it's his umbrella?

Read this strip at gocomics.com.

This is a silly strip, it doesn't really have a strong gag but it's visually appealing.  One has to wonder about the practicality of a dog owning an umbrella though.  How does Snoopy close it?

April 27, 1953: Dig that crazy rain

The sketchiness and wavering line of later Peanuts has a charm that goes well with the personality of the strip, but let’s never forget that early Peanuts showed great technical ability.  We saw that back in the golf strips a couple of days ago, and we see it again here in this wonderful depiction of a rain storm.

The thing that makes it really appealing to me is the darker hatching used to represent obscured scenery in the background.  It’s wonderfully suggestive without being too precise.  It actually looks better to me this way than the backgrounds that would usually be back there.  It must have taken a long time to draw.

Here's some more rain from a few days later, just because I probably wouldn't link to the strip otherwise:

Sunday, September 14, 1952: I'm a success!

This is one of the best early strips I think, it's just really funny and original IMO, despite a couple of pretty weird quirks. Its action can occur only because Lucy never looks down. The really weird thing about it is how Charlie Brown doesn't tell Lucy the cause of her "success," that she was being held up by Snoopy. The whole thing has an air of allegory about it.

Lucy's phrasing "I'm a success!" is very odd. It's funny partly because of its oddness, but it is oddly specific, like it might be a reference to something in Schulz's life.
