Origin of the Shield Shape in the Solar Folio of the f85-86 Foldout

But I suppose that the optimists (me) will feel vindicated by the fact that the Retracer got half the characters perfectly retraced, completely hiding the original ink.  While the pessimists will note the fact that, on half of the characters, he was unable to do so...

I'm under impression that we are looking at different scans, again. I can count maybe 15 characters that are retraced without leaving the original ink visible, out of approximately 110 total retouched. I would call this a very accurate retracing job, though.
