Late ’70s, early ’80s covers for Frank Herbert’s Dune series. Cover art by Bruce Pennington. Books published by New English Library Books.
There are a ton of different editions of the Dune series, as you can see on arrakis.co.uk. I really like the Hebrew and Brazilian editions, but my favorites are four UK covers illustrated by Bruce Pennington.
The titles of the books are set in Giorgio. Giorgio is like a psycedelic slab serif. The tagline text has been set in Monotype Grotesque.
