I wasn't at San Diego, but as far as pulps go I had a pretty good weekend. Here's the first half of my finds, I'll share the others in a day or two:
This one has Ray Bradbury's "Mars Is Heaven", from the Martian Chronicles and one of his best known stories.

I already had a copy of this one in even worse shape; it's noteworthy for the Fredric Brown (they spell it right inside, at least) story and the only story John D. MacDonald did for Planet.

The dealer had this marked as an early Philip K. story. (Insert brief filter rant here.) Which is correct, as far as it goes. It actually has his first ever published story.

This one isn't as impressive on the writing front, although it does have a John Jakes story for those who like his stuff. The impressive bit is who drew an illustration for the Jakes story. Sorry about the scan quality, it was as flat as I could get it without risking damage to the book.
I know Wally did a fair number of illos for the digests, Galaxy in particular; but this is the only time I've seen him in a full-size pulp.

And that's the Planets I got this weekend.
