If anyone can pin a date on them or where they were used I would be most grateful and will of course update the blog accordingly.
Here's a interesting update following Michel Van's comment that the bottom images was used as the cover of Inherit The Stars by James P Hogan. Now this is curious because that's exactly what the image reminded me of when I first saw it...
...but I never once thought that the same book might have two such similar covers. However, there it is...
...the proof in the publishing. The first was by Darrell K Sweet which I had previously blogged as being from 1977 so I'm going to take a punt on that being the original as Michel Van dates the John Harris cover at 1989.....unless anyone knows different?
Cheers for that.
