D, you are quite right about the 3 first editions of RHTRBC&SAI. I have the tipped in edition (ironically, stamped "Discarded by US Air Force") which is the second first edition, as well as the third, which was the proper first edition.

The first first edition (the one without any dedication) is very rare and therefore valuable to book collectors. I'd snap one up if I could, but I'm not lusting and when I think about it, it's one of those things that seems silly to value. Of course some day people may say that about humans who loved paper stained consistently with ink...will
