You might try this online archive.

The orbiters captured tens of thousands of images so you may need to work on narrowing down the capture date or surface coordinates.

Thanks, I didn't know this database even existed online. I tried limiting based on altitude (the Orbiter must be at least 8,000km above Mars) but that field might just be for Earth orbit missions. As I understand it, the Orbiters had a high apogee that was later lowered.

If anyone has that magazine, perhaps they could kindly check to see if there is an image number in the credit or perhaps an identification of which Orbiter took it.

It's possible the image was taken on approach rather than in orbit. NASA SP-441 "Viking Orbiter views of Mars" has a view of the entire hemisphere with the terminator in a similar position that is almost right but isn't the one you're looking for.

It might be that the cover shot is a cropped version of one of those approach views.

On edit: On the montage of approach shots shown here the one on the left seems (shown lower down on the page labelled) to match up with the cover shot.
