If you had bought Theatre de Marionette season tickets for the little ones this year, you could have assured them of seeing fun, professionally done, European-style puppet performances of such kiddie classics as Pinocchio,The Little Mermaid, Aladdin & His Lamp,Peter Pan, and The Littlest Angel. This is not Freddie the Clown or Howdy Doody stuff. Russian puppetry artist Tina Gromova, who toured Eastern Europe and Asia with the renowned Moscow Puppet Theater, is this year's headliner. Recommended for kids 3-4 years old and up. Individual tickets are still available: $8 for adults, $7 for children.
