In researching this font, I looked at hundreds of pages of his drawings and letters. There was a range of clarity and character-formation; I've patterned this after his more deliberate lettering rather than that of his correspondence; the latter was useful for numbers and other characters. I redrew each character with the rough texture of pen, brush, or even chalk lines.

There are two weights, each with a number of alternates. Couldn't resist including my versions of four of his sketches, also seen here in the page background.
