Original Toronto Star caption: The good citizen of the month, Mark Zimmerman, entertains patients in the Hospital for Sick Children by making sculptures out of such unlikely things as dental cotton and tongue depressors. A dentist, Zimmerman also subtly gets across the message that youngsters should brush their teeth. He's put on more than 800 of his shows in hospitals, old people's homes, service clubs and youth groups, he also holds the Metro record of 137 blood donations to the Red Cross.
