More HPL in Astounding Stories

A story by H.P. Lovecraft appeared twice in the pages of Astounding Stories, the first of which was At the Mountains of Madness, serialized over three consecutive issues (February–April 1936). Later that same year, in June, another HPL story appeared, "The Shadow Out of Time," which is, in some ways, a thematic sequel to At the Mountains of Madness. (They both feature Professor William Dyer of Miskatonic University, for example).

Like its predecessor, "The Shadow Out of Time" was published with multiple illustrations, several of which are quite worthy of examination, like the one that appears opposite the first page of the story. Here, you can see two examples of the Great Race.

The next two illustrations depict several non-human species Professor Peaslee presumably encounters while a guest of the Great Race. Take note of the creature in the middle, which is similar, though not identical, to the artwork of the Old Ones (Elder Things) that had appeared in previous issues.

The checkerboard flooring in these illustrations is quite striking, though I don't believe Lovecraft's text suggests anything at all like it. In fact, as I recall, the floor is made up of octagonal stones. 

Here, we see the Great Race again. I find the fact that, despite their advanced technology, they still use books – and ones suitably large for their size. To be clear, this is a detail that Lovecraft himself includes in the story, so it's not an embellishment of the artist. That doesn't make it any less silly, though.
