After high school, he joined the Navy for 3 years, serving in Guam, where he drew a comic called Boondocker for The Navy Times.
He returned to his home state and enrolled in the University of Georgia Lamar Dodd School of Art under the G.I Bill, where he drew for the student newspaper. Before long, his teachers were encouraging him to go to New York to pursue his art career. He moved north and enrolled in classes at the Art Students League.
After moving to New York in 1949 and studying at the Art Students League at night, he made his first entry into the art field as an inker for a comic strip, “The Saint.”
He got his start in 1950 selling drawings to EC Comics, which published horror fiction titles like “Tales From the Crypt.” Two years later, amid an outcry over the potentially harmful effects of violent comics on children, the company started what became Mad magazine, edited by Harvey Kurtzman. Mr. Davis was a member of the “Usual Gang of Idiots,” the nickname for the crew that put out the magazine.
He was soon heavily involved in comic art of every description, and became one of its top practitioners for Mad Magazine, Trump, Playboy, and many other publications.
