Ernest Chiriaka (1910-2010) and his first pin-ups were for Esquire in 1952. 

Working in gouache, he produced works that had very distinctive skin tones, especially in their printed form. Chiriaka contributed pin-ups to the 1953 Brown & Bigelow Ballyhoo calendar and later did three additional pin-ups that the firm published as seperate calendars.
