Harley-Davidson filed a lawsuit yesterday in Federal District Court in Manhattan in response to a suit that Lorillard filed last month in the same court accusing Harley-Davidson of frustrating the licensing agreement, which began in 1986. Harley-Davidson's countersuit asserted that an unspecified Lorillard campaign for Harley-Davidson cigarettes was being aimed at children. Avrett, Free & Ginsberg in New York, which creates campaigns for Lorillard brands like Kent, is also agency of record for the Harley-Davidson cigarette. The agency is not named in the suit.
