Hi! Richard Powers is such a unique cover artist that you could recognize a SF or horror paperback from a mile away. Powers and Paul Lehr are my 2 all time favorite cover illustrators/artists. These 2 guy dominated U.S. paperbacks back then. It's all a matter of taste, but I've always found Mr. Power's covers be unsettling, arresting and unforgettable and Mr. Lehr's covers to be beautiful, arresting and unforgettable. Seriously, you can recognize a Richard Power's cover from a mile away.
