The Experimental History of Scifi Book Covers (Plus Crime Covers Link)

One of Frank R. Paul's beautiful alien ecosystems,
from the back cover of Amazing Stories for Aug. 1941.

In my previous post discussing Moorcook's essay on Bradbury's Fahrenheit 451 I mentioned how much I love these overviews of SF authors, illustrators and their works. Here is another from io9 a video on (The Experimental History of Scifi Book Covers) put together by Nerdwriter?

A selection of covers by Frank R. Paul

Some of my favourite publishers and illustrators are discussed, including Frank R. Paul, Richard Powers, and the myriad artists who worked for Penguin books over the years. I am still disappointed that our trip to London generated no covers by Alan Aldridge, but just like yesterday's link I was again compelled to return to my shelves and see what I could find.

Two Paul Lehr covers, Entropy is by Fernando Fernandes.

Two Richard Powers covers, the Penguin is by Brian Kneale
