Back in the halcyon days of yesteryear (i.e., our individual childhood years, which most of us consider our personal halcyon days), everybody gave away stuff to promote their businesses. Banks offered up toasters, blenders, and other shiny functional items for a savings account established with them. Groceries stores gave away food stuffs for coupons ... and dishes like Acme today if you carefully followed the special offer rules. If you were persistent, you could collect a whole set of dishes, china, Corning Ware, or encyclopedias, whatever suited you.
Many of us remember the Anchor Hocking or Libby glasses given away at gas stations, along with a variety of useful freebies like key chains. You got a glass when you filled your tank. If you were a regular customer, and that was the intent, you could end up with a complete set before too many months had gone by.
Then there's the free stuff you could get in boxes of food--ceramics included, in Cracker Jacks, and through your Jewel Tea door-to-door salesman. All of it was designed to create customer loyalty, at least until a complete set of something or other was obtained. Good luck, Acme, and thanks for the blast from the past!
I wonder what blast from the past will be next ... oh yeah, it's already here, the wrist watch communicator! And that's the five minute response.
