I've loads in my library, I try to get original cover editions wherever possible because second print editions covers tend to be bland rehashes of popular film or tv art. I find the ones like used to grace the covers of astounding magazine (which later became Analog) truly inspiring because the artist was encouraged to read the stories and base his / her art based on it.
if you want any photographed let me know, I've almost a full collection of amazing wonder stories (hugo gernsback, editor) the later amazing mag then the famous (infamous) analog mag. I have most editions of Omni too but they currently reside at my wifes place in the fire safe.
Foss-style 70s sci-fi paperbacks were the first thing that sprang to mind when I saw this image, you've really captured the character of them here. I have to say that those old novel covers were (still are) a huge inspiration to me too.
