Beautiful 70s Scifi Art: http://70sscifiart.tumblr.com/
I have a large collection of old science fiction books (60’s and 70’s) from spending a lot of time in second hand book stores.
Growing up before the internet and the explosion of the genre in the 90’s that use to be the only way to find new books or authors.
The art of sci-fi book cover has certainly lost something...if only for being more pc.
And everyone else can go home. ;-)
