From the yellowing paper on which it’s printed, you’ve probably guessed that it’s from the great American tradition of pulp illustration and you’d be right. This one appeared in Science Fiction Quarterly for February 1957, illustrating a story “BEMA” by Wallace West (1900-1980). The artist, sadly, is uncredited.

It contains a story by Phillip K. Dick, among others.
Virgil Finlay?
Seems stylistically possible, though I would be surprised if an artist of his stature would have been left uncredited.
