In honor of Wimbledon, here’s a Horwitz cover for 1964’s The Love Game by Donald Hann. We had to search far and wide for a good tennis cover, but finally found this one at a webpage maintained by New Zealand’s University of Otago, which also has many other covers worth viewing. Donald Hann was a pseudonym belonging to author Ken Macauley, and the art here is uncredited.
It’s the unseeded players that really need to watch out.
