In addition to the beautifully lonely, and unfortunately uncredited, cover of Orphans of the Sky at left, I also picked up a later variation of the early, vaguely ominous The Puppet Masters, plus a Revolt in 2100 done by the unmistakable Gene Szafran.
As long as I was on a roll, I then went back to my Clifford Geary Between Planets, and at last I scanned his half-dozen interior pen-and-ink drawings. Fun!
I hope you may enjoy,
