I've seen this image online several places (for example, here
). Does anyone know the original source?
I thought it must be "The Stroke
"—but I don't see it in my (older) copy.
I have also looked at this older version ("The Stroke of the Pen
") but I don't see it there either!
I also have "Letter Letter
"—but I don't see it in there either?
I was hoping to credit the image properly in a slide lecture...
