Original packaging concept for "insanity-inducing ice cream" inspired by H.P. Lovecraft's story, "The Call of Cthulhu." From the package: "The great old ones knew this day would come: when Hastur the Unspeakable and Azathoth, atop his throne of chaos, would gaze serenely as you consume a whole pint of ice cream so hideously delicious that you will not retain your sanity." Photos: Kate Weybret.
