What is the title of an older book that was a collection of sci fi artwork?

[pballingdove]

It includes a picture of war of the worlds, one of some pure energy being, one of an empty space helmet reflecting another image, and one of bipedal bears who carry people on their backs, as well as many others. I am not sure how old the book is, but I know I had it as a kid in the early 90's.
