From the Practical to the Digital of

Though the original artwork is done by hand (graphite, ink, and paint on paper), reproduction for print or some other kind of mass display method (such as this website) is necessarily a digital process involving scanning hardware and image-manipulation software. The originals are made with this purpose in mind, i.e. to be correctly interpreted and edited during post-production, rather than to be viewed live, in person. This means that the originals might have unsightly pencil marks, inconsistent ink-coverage, painted corrections, notes in the margins, pasted/taped sections, etc., which are not visible in reproduction. (Think of this as being analogous to live action film: wires, motion-capture marks, and blue/green screens may be obvious and necessary on set, but are not meant to be seen by the audience.)

For the sake of this demonstration, the first page of Volume 2 is used, as thoroughly as Charles's records allow.

The initial writing for this page (and soon afterward), done as thumbnail drawings in a sketchbook.
It only needed to be legible to Charles himself.
He writes comics in this way, as much as possible, because it is ultimately a visual medium.

A quick reference for panel-layout of this page, done after the thumbnailing.
From here, the page was ready for penciling on the final board.

Because of lacking scanning equipment at the time, and erasing the pencil marks after all of the ink had dried (for cleanliness of scanning), the fully pencil-only version of this page no longer exists in any form. Though having a record of it would be useful for archival purposes, the penciling itself is only a transitory stage between illegible thumbnails and scan-ready ink drawings.

Notice the inconsistency of the black areas, as well as the various gray spots.
This is something like how the original board looked, upon the ink-drawing being finished,
except that the board itself is actually much larger than it is intended to be displayed on this website,
and the scanning process creates some blemishes of its own, due to debris, scratches, etc. on the glass.

The artwork once it has been properly scanned, corrected, cleaned, and cropped,
as well as reduced from original size (for reasonable display on a computer monitor).
A white border is added, for the sake of distinguishing the black edges of the image
from the black background of this site.
