The early 1950s saw the invention and introduction of “talking storybooks” that were dreamed up by Bay area native Bruce Sedley. The San Francisco zoo was the first American zoo to use talking storybooks and at the same time introduced the ingenious elephant shaped key called Trunkey the Elephant.Â Cleveland, Detroit, Philadelphia, Cincinnati, San Francisco, New York (Bronx Zoo) all had their own talking storybooks and elephant keys. I remember bringing the key to the Cleveland Metroparks Zoo as a kid â€” something really special that I look back upon fondly. When I was home for the holidays my dad unearthed one of the keys our family had from the late 70s. It had been in his desk for the last 30 or so years. I’m glad dad never throws anything out. Anyone out there remember these things?
