I started by picking Rockwell for my body typeface. While it generally isn't used as for body copy, with some extra leading I thought it had a nice presence to it, bold and geometric like Koenig's work. I decided to go with line breaks rather than indents to also mimic the geometric modular qualities of Koenig's style. I then choose Azkidense Grotesque from my display for contrast, but still geometric.
My grid is a 4 column by 16pt.
more to follow very soon
