Leffler?s zoo campaign brings measurable results

In its first campaign for the Maryland Zoo in Baltimore since landing the account in October, Baltimore?s Leffler Agency is saying that the firm?s work has already made a significant impact on attendance at the longtime Baltimore institution.

During the zoo?s opening weekend, Heather Sable, an agency spokeswoman, said the zoo saw attendance of more than 21,000 people, compared with attendance of only 2,600 for the opening weekend in 2005.
