Can any of you type geeks give me an example, or several examples, of a good type superfamily with the primary design serif (better Old-Style) and the companion design slab-serif. I only know of two such superfamilies: Erik Spiekermann’s and Christian Schwartz’s DB Serif / DB News, or Jean-François Porchez’s Le Monde Livre / Le Monde Courrier. I know there are more styles to either family, but I am primarily interested in the serif/slab-serif relationship. I suspect there should be more similar designs out there. Thank you in advance.
