The Southern California Edison advertising chip is probably from the 1950s. It was probably for a key chain. Still too young for Seymour's book, but maybe in another 10 years??

Here a clip from a historical article in the LA Times in 2001:

To keep demand high, the electrical industry launched the Live Better Electrically, or LBE, campaign in March 1956. It was supported nationwide by 300 electric utilities and 180 electrical manufacturers.

The campaign got then-actor Ronald Reagan, the popular host of "General Electric Theater," to take his television audience on a series of tours of his and wife Nancy's all-electric Pacific Palisades home.

An in-house GE sales pitch declared that "by Thanksgiving, there should not be a man, woman or child in America who doesn't know that you can 'Live Better Electrically' with General Electric appliances and television."

Any idea of the source of the red "C" chip? It's a light embossed chip of paper or fiber.
