Two paperbacks by Robert A. Heinlein (1907–1988), “the dean of space fiction”, reissued in 1964 by Signet Books. Both books feature Inserat-Grotesk for the title, set in big lowercase letters and with one word per line. The title type clasps around the synopsis in News Gothic. The author’s name is added on the left, set in a rotated line of Ludlow’s Stencil.
