Since the captial sharp s is easily available to the public, I see it popping up everywhere in
German publications, mostly in an all caps environment. I have a small collection of it (on paper).
The use of the capital sharp s in German is not only a historical artefact, it is recent and modern.

However, the example is also somewhat misleading. The book in the
picture is clearly quite old. The Duden that was cited is new. I checked
with "Der Grosse Duden" on Amazon, but all the books I found had the
officially correct spelling. On the other hand, I remember that when the
upper-case sharp s came up for discussion in Unicode, source material
showed that it was somewhat popular quite some time ago (possibly close
in age with the old Duden picture). So we would have to go back and
check the book in the picture to see what it says about ß to be able to
claim that Duden was (at some point in time) inconsistent with itself.
