From Wikipedia:
Turning On is a collection of thirteen science fiction short stories by American writer Damon Knight. The stories were originally published between 1951 and 1965 in Galaxy, Analog and other science fiction magazines.
This is the first paperback edition, published as Ace G-677 in 1966, with cover art by Jack Gaughan and obliqued Caruso Roxy for the type.

While the blurb on the front cover uses two widths of News Gothic, the spine lettering is in it bolder sibling, Franklin Gothic.
