Talented magician, Robert Day, asked the audience. He held up three large cards: two kings and one ace. The audience was wild and shouted "king" or "ace" but Mr. Day's reply was "library card". As a librarian, I was very impressed by his library card compliment and that reading magic books from the library was how he learned how to perform magic tricks.
I spotted one child hold up his new plastic library card and said "I have one of those, see?!?" Mr. Day's program is high energy and the audience absolutely loved the magic and the candy was a nice touch too!
