I was wondering when it became a custom to include the name of the book's typeface in the colophon... I can't remember seeing a book from pre-WW1 in which the typeface was named -- which is no surprise considering that the variety of available faces wasn't as wide as it is today, and people would call their faces things like "Gewöhnliche Antiqua" (plain roman).
The oldest book I've seen doing this is from the (late?) twenties, IIRC, so my initial idea was that there might be a correlation with the paradigm shift(s) in typography (Morris, later on Tschichold). But even that seems like an exception to me; it looks more like a post-WW2 thing, but I'm not sure though, and the answer might depend on what parts of the world we're talking about. I could imagine, for example, the Kelmscott Press people did it, too...
