Karnak is a slab-serif typeface designed by R. Hunter Middleton for the Ludlow Typograph company and issued in the period 1931–1942.
[1][2] Karnak is a "geometric" slab serif, reflecting the style of German geometric sans-serifs (in particular Futura) which had attracted considerable attention in the United States and adapting the design to the slab serif structure.
[3][4] Middleton also designed a loose copy of Futura, the sans-serif Tempo, around the same time.
[2] It and other similar designs were popular in American printing during the hot metal typesetting period.
[8][9] It is an adaptation of the sans-serif Neutraface designed by Christian Schwartz, influenced by Middleton's Tempo.
