I want art on the back cover. In my head I see a tribute of sorts to Erol Otus' back cover for Deities & Demigods.
In any case, the oval shaped text area will be incorporated into PG's back cover design. FUN FACT: The green god-thing on the left appears in Geof McKinney's CARCOSA.
UPDATE: The eminently talented Paul Ballard is currently working on the back cover art.
