Peter the Rabbit, pet of Mrs. Louise Bailey's sixth graders at Ann Arbor's Pittsfield Elementary School, has been busy recently, watching an "International World's Fair" presented in "his" classroom. The students set up booths containing the artifacts of a number of exotic places - including Hawaii, Italy and Jamaica. All the other students in the school were then invited to the fair for a tour and to vote on the best booth. Manning the Hawaiian booth are (from left) Karen Hawks, Susan Eisses, Wade Gurney, Carl Jones, and, of course, Peter.
