Anyway, with the exception of the last one, this is a nice little collection of horror anthology paperbacks from the UK. I bought them in Petaluma, California, where a guy was selling them in his antiques kiosk for $1.00 apiece.
Besides being a fine writer, August Derleth was also a publisher. His imprint, Arkham House, anthologized many of the great Weird Tales writers like H. P. Lovecraft, Frank Belknap Long, Clark Ashton Smith, etc.
Dashiell Hammett is most famous for his detective stories, but lending his name to a horror anthology probably helped sales.
I threw in the Pan Book because until I saw the Gold Medal logo and 50¢ price I thought it was from the UK. Well, scare me with a screaming skull if that don't beat all! Nice cover, though.
