These science fiction cover galleries are becoming so ubiquitous it hardly seems worth cataloguing a new discovery. However… This pair are from the George Kelley Paperback and Pulp Fiction Collection at the University of Buffalo Libraries:
The UB Libraries’ George Kelley Paperback and Pulp Fiction Collection includes over 30,000 pulp fiction books and magazines. A selection of cover art images, representing more than 500 crime fiction and science fiction volumes found in the Kelley Collection, is featured in UBdigit. Colorful and dynamic, the cover art highlights a variety of artistic themes and imagery, reflecting the social and cultural trends of the period in which these covers were created. (More.)
The documentation is rather scant, unfortunately, but I recognised the Driftglass cover as being by Bob Pepper while the Brian N Ball (who he?) cover is a splendid piece of work by Kelly Freas which can be seen at a larger size and free of type here.
