A 1967 promotional card from Consolidated Analysis Centers Inc. of Santa Monica, the company now called CACI International. The back explains that this “Enchanted Punch Card,” used as the first card of a program deck “so the letters ‘C.A.C.I.’ can be seen by the computer,” marvelously enhances your likelihood of success. It ends with a warning: “Do not use card with this side forward!! The effect has never been tested!!!!”
