H. P. Lovecraft’s Letters to Henry Kuttner, cover and two inside pages
This chapbook was published in a limited run in 1990, and yesterday, I bought a copy off Ebay. I’m really excited to read it! It includes ten letters Lovecraft wrote to Kuttner over the period of the year leading up to Lovecraft’s death. (As you may already know, both Lovecraft and Kuttner died young—at 46 and 42, respectively—about thirty-one years apart in time.)
The text on the second picture is part of a letter, I assume. The drawings are all Lovecraft’s. See, “as a Californian it is clear that Kuttner knew nothing about New England history and topography”*, so Lovecraft drew him out some maps and shit so he could write better stories in the Cthulhu mythos. (Why Salem and not somewhere in Rhode Island? Because Kuttner was working on a story called “The Salem Horror” at the time. o/)
*That is an actual quotation from the actual introduction of this actual book. (The Ebay page includes the first page of the intro, but it cuts off in the middle of a sentence and doesn’t seem like it’s worth putting up here.) I AM SO EXCITED TO RECEIVE THIS THING.
Black God’s Kiss by C. L. Moore (pub. 1977), signed by Moore and Alicia Austin, the book’s illustrator
I’ve bought twenty books by C. L. Moore and Henry Kuttner in the past ten months (most of them at the rock bottom-est used-book prices I could find, for the record), and this one is by far the most beloved in my collection so far. Not only is it a signed copy, the illustrations in the book are absolutely beautiful. They’re the closest I’ve seen to how I imagine Jirel of Joiry in my head. At some point, I’m planning on (very carefully) scanning them in and posting them, though I’ve been a little busy lately.
Next goal is to acquire a book with Kuttner’s signature, which is going to be a significantly more costly endeavour than this was, being as he died almost sixty years ago. But someday, someday. :|

Man Drowning - Henry Kuttner (1952)
Goddamn, is that a striking cover. Here’s a review from the Springfield Republican, July 6, 1952:
Mr. Kuttner writes powerfully and well of a man’s moral deterioration into a pawn of murder with a skill which holds promise. ‘Man Drowning’ is packed with action and written with the clarity of a polished movie scenario.

If anyone knows where to find the photograph this was cropped from (if there is one), please let me know! I’d really like to see the full thing if possible, much as I enjoy his ascot.
