While Ray Bailey is definitely the main artist on this book, some pages look strange, as if someone else worked on the pencils. Compare this book to the other Bailey Steve Canyons and you'll see what I mean. Page 10 is a good example. I also get the impression Caniff didn't finish all the Canyon faces like he did in other Canyon books. Yet I'd swear Caniff did ink a non-Canyon panel here and there.
All this may simply be the result working too fast--a number of pages seem rushed. Puzzling.
