Here's a 1966 Reader's Digest Condensed Books story illustrated by Neil Boyle. I don't know if he did others - this is the only one I've ever found. But he's certainly in great company in this particular volume; it also contains stories illustrated by Bernie Fuchs, Howard Terpning and Francis Marshall! (Don't worry, we'll be looking at those others stories some time soon)
