Nothing says "I love you" like a 1978 Casio Mini Card LC-78 Handheld Electronic Calculator, right?
This credit card-sized, lightweight electronic calculator has an aluminum case, plastic keys and display cover, a plastic circuit board, and metal circuitry. Just in time for Christmas, a December 1978 advertisement in the Los Angeles Times listed the Casio LC78 and other "math machines" as the ideal gift "For someone you love who loves being accurate." The romantically-minded could snag the Casio for as low as $29.99.

For the person we love who loves being accurate, please send us exactly twelve long-stem roses instead. THANKS. ?
