I just came across a condensation of This Rough Magic that appeared in the Chicago Tribune! They published the story in 18 installments running from Nov. 8 - Nov. 24, 1964, which must have been just as the book was released in the U.S. The illustrations are very 1960-ish.
The quality of the images isn't that great, seeing as they're from a newspaper, but it's still fun. I especially love the taglines that they put at the top of each installment: "Bullets Shatter a Peaceful Vacation," "Spiro Tells of His Brush with Death," "Keeping a Killer off his Victim's Trail." And the best of all: "Suspense Winds an Ever Tighter Coil as Lucy Waring Creeps up like a Ghost from the Sea on the Spy who Tried to Kill Her".
I'm posting the first two pages, as I think that's all I'm allowed due to copyright. I located these images using the ProQuest Historical Newspaper database.
