Who Wants a Tab?

It's a good thing I love the idea of time travel, because it is now 1974 inside my office. Yes indeed, this is our "new" vending machine. Straight out of an ad in a vintage copy of Popular Science. Its even got wood paneling. On the plus side, if you shake it, it probably dispenses free cans.  On the minus side, why is that baby wearing lipstick and drinking a soda?
