In the 1970s I was a member of the Science Fiction Book Club. Whoever the art director was at the time, they were producing some excellent covers. I still have the Edgar Rice Burroughs Barsoom novels with Frank Frazetta covers and illustrations, but I somehow lost The Best of Fredric Brown (1976) with this Richard Corben illustration of a Yeti embracing an explorer. I probably let a friend borrow it, and it never made its way back to me. I could buy a used copy on Amazon for a few bucks, but I already have Kindles of his short stories.
One of my favorite Brown stories didn't appear in this anthology. It's called "The House." It's just 3 page long. Here's a PDF scan from the August 1960 issue of Fantastic Science Fiction Stories. It reminds me of descriptions in an Infocom text adventure. Here's an essay about the story.
