I found the original publication of Heinlein's "The Man Who Traveled in Elephants," which was titled "Elephant Circuit" when it first came out in the October 1957 Saturn Science Fiction and Fantasy. I had read the story probably only once, a more than 30 years ago, so I re-read it in the original pulp, which was nice. The cover art--apparently for a story called "California is Doomed!"--is crazily garish and now is posted on my "Pulp Magazines" page.
I also picked up early 1950s book reprints of Heinlein's semi-rarely-discussed "Water Is for Washing," one a hardcover with nifty cover art of a man and also a woman, both rifle-armed, moving through palm trees, and one a paperback with some rather interesting and casual ethnographic teaser blurbs on the back. Now, I confess that the story's original publication in the November 1947 Argosy was something I had been looking for for a long time to no avail...and suddenly it turned up in a completely random venue. Excellent. The charming Peter Stevens double-page interior is here, but of course a fuller shot of it, along with the cover art and more, can be found at the good ol' "Pulp Magazines" page.
