Though the Prang served a variety of functions (“a container for cufflinks…, an aspic mold…, …a delicious and not-too-filling hors d’oeuvre” — from The Curse of the Mysterious Prang-Prang, Box 13, Folder 11), it was primarily a 3-D calendar designed by Chermayeff & Geismar Associates in the late 1960s and early 1970s for Crafton Graphic Company. Despite my distinct lack of spatial visualization skills, I still managed to assemble the Prang in less than 30 seconds. I just need to decide what wine will pair best with this thing.
