Dune and Doon by the same artist, Doug Beekman.
If you haven’t read National Lampoon’s Doon, I highly recommend it for any Dune fan. It’s a book where the spice is beer, the worms are pretzels, the Kwisatz Haderach is the Kumquat Häagen-Dazs, CHOAM is NOAMCHOMSKI, and the litany against fear is the litany against fun.
I must not have fun. Fun is the time-killer.
