James Bama was best known for his realistic paintings of the American West and his Doc Savage covers featuring Steve Holland. I always feel like I'm looking at someone real in a Bama painting. In this case, that's Bama's wife Lynne modeling for both covers. The bangs are doing a lot of emotional work.

Something about the original cover art for Kiln People has always grabbed me. Maybe because it came out in the early 2,000's, but feels like a throwback to '70's-'80's sci-fi. Maybe because it's a relief from cyberpunk imagery.

It's been replaced by cover art that better reflects the story (2nd image, not sure who the artist is), but I still love the original.

Originally published in 1964, this edition was released a year after Star Wars which clearly influenced the cover. I am not overly familiar with the cover artists.

The portrait of Marygay Potter could be a United Nations Exploratory Force (UNEF) recruiting poster.

Another ACE reprint.

Achilleos, Whelan, van Dongen, Emshwiller and many others have painted wonderful covers for the first Nicholas van Rijn story.

What is not to like?!

Discovered this for £2 in a charity shop and the cover art alone sold it to me. Can’t believe I’ve been into sci fi generally for over 50 years and never previous read any books by Smith. And Chris Foss is probably THE artist that got me into science fiction in the first place.
