Pete Millar worked as an engineer in San Diego, before he went to LA and started working as a cartoonist/comics artist. Since 1953, Millar was one of the leading artists of hotrod cartoons and comics, published in magazines like Rod & Custom, before he began his own magazine CARtoons together with Carl Kohler. When his cooperation with Kohler folded, Millar created Drag Cartoons. Millar was a racer himself, and his former experience as a aerospace engineer and technical illustrator made his hotrod artwork very realistic and detailed. When Drag Cartoons fell apart, Millar went to Sweden. After three years, he returned to California, where he went on to produce annual editions of newspaper-sized full-color Drag Comics on newsprint in 1971, 1972 and 1973. Millar then left the field, although he kept doing cartoons for occasional racing events. He was one of the first to put illustrations on sweat- and t-shirts.
