Can’t leave the letter R without a couple more illustrations, both from the Catich volume mentioned before – The Origin of the Serif. Both are brush drawn. The first also shows the various elements of the letter, while the second is simply an exercise in brush-manship, of which Catich (and more about him in another post) was an expert. It is also the cover of the paperback edition I have. Will also have more to write about brush lettering, and its relationship to stone carving. I also touched on this before.
