Dig that crazy Zip-a-Tone!
Actually it was done with a Photoshop filter. I don't think Zip-a-Tone has been made since the early 1990s. This reminds me that I haven't described my creation process.
I draw these pages on paper (often the back of random scrap sheets, which I impulsively collect) with a blue pencil, then ink them, letter them by hand & scan them. I do most of the black fills and toning in the computer.
