Inspired by Grumpy Andrew, who traveled to Las Vegas asking, "What Would Prof. Oddfellow Do?"  Speaking of Bigfoot, this actually exists: the Bigfoot Bible.

The highly rare Fortello Crystal Ball sold in 1953 for $4.95, which the inflation calculator says is more like $55 today.  Made of glass (approximately 5 inches in diameter) and filled with a thick black liquid, it was crafted by Larno Novelties of New York.  It worked like a Magic 8 Ball: when shaken and turned upside down, little playing cards inside the ball floated to the top to tell one's fortune.  Its full name was "Fortello: The Gypsy Crystal: A Fortune Telling Game."  We found a photo on an auction site of one owned by a magician.  The ads are from Mystic Magazine and Fate Magazine, 1954, when it had gone down in price to $3.75 (about $42 today).  Larno Novelties is itself so little known that we could find only a single ad mentioning them by name, for a lucky fishing lure.
