Freebairn & Co. is growing, with a new assistant art director and an agricultural client. Jason Stewart was named Assistant Art Director. The former Assistant Art Director for Walcor Industries in Pennsylvania will design brochures, spec sheets, and other advertising for Aventis and US Filter Surface Preparation. The Atlanta-based advertising, marketing, and public relations agency also won the $1.5 million national print campaign for Aventis CropScience, a company born out of the merger of AgroEvo USA Company and Rhone Poulenc. The six month campaign “New Ideas for Agriculture” began in January and is designed to position Aventis CropScience as a top global agricultural company. Aventis specializes in crop protection, biotechnology, and the seed business. Freebairn & Co. developed the communications program for AgroEvo USA for 16 years prior to the merger.
