Maria Bull is the owner and trustee of the award-winning international motorsports publisher David Bull Publishing, and she is the sister of David Bull, founder of the company. David founded the company with the goal of producing the highest quality motorsports books—well written, beautifully designed, and produced to the highest standards. The company most recently released the Publisher's Edition of Luca Dal Monte's book "Enzo Ferrari: Power, Politics and the Making of an Automotive Empire," whom I recently had on Cars Yeah.
