The business of designer Roy Kuhlman. According to the Kuhlman Archives:
In 1964, [Roy Kuhlman] formed Kuhlman Associates to serve industrial clients in the areas of advertising, promotion, audio-visual and studio photography. Kuhlman later said that he created the new business name because he thought it made him sound more professional, as it implied that he had employees.
As of this writing, no employees or partners of Kuhlman Associates have come forward. Nevertheless, some Grove Press covers credited to Kuhlman Associates appear to have design elements that lend validity to the claim that he had employees or partners.
