“The King Penguin series, which covered art, science, leisure, and world history, was one of the first series to be printed in color and in hardcover by Penguin (...) Tschichold decided that the overall redesign of the King Penguins would emulate the prominent and much admired Insel-Verlag (Insel-Bücherei) picture books from Germany. For King Penguins, Tschichold used unconventional classic typefaces; for example, Centaur, Pastonchi, Poliphilus, Scotch Roman, Lutetia and Walbaum.”
