I also picked up a copy of the 30 August 1947 issue of Collier’s, which has the rare-ish “Flight Into the Future” article written with Cal Laning, which discusses the type of U.N.-controlled orbiting deterrent atom bombs that turn up in Heinlein’s 1948 young-adult novel Space Cadet. I find the Rolf Klep interior art charmingly draftsman-like, as always.
Oh, and the reprint of the Beyond This Horizon originally published in 1948 by Fantasy Press? Well, I already had a 1948 Grosset & Dunlap with the original A.J. Donnell cover art...but what I didn't realize was that the slightly earlier Fantasy Press also had 3 charcoal interiors by a fellow named Robert Breck. Great. Now, the way I realized this was not by buying the First Edition Library reprint—which actually came second—but by seeing one of Breck's original pieces for the book, namely the one appearing between pages 148 and 149, available at auction... When something like a Frank R. Paul or a Frank Frazetta goes up for sale, prices are huge, and even an Emsh can be deadly serious money. This Breck, however, ended up being not too bad at all, really, so I was able to get it.
All the pieces mentioned above, along with the 20 others I didn’t specifically name, now can be found at the appropriate pages of my Heinlein Cover Art galleries, of course.
