This was the first Talking Storybook Key patented by Bruce Sedley (see patent links on side bar) used at the Children's Fairyland in Oakland's Lake Merritt Park. The first keys were gold and came in a Magic Key box, along with a tag listing the 15 Fairyland Storybooks. Click each picture to see close-ups.
This crown-top key later was issued in other colors, including yellow & blue as shown. Have you seen other colors?
