Lee Holley is best known for the 'Ponytail' strip, which he drew from the 1960s through the 1980s. He studied at the Chouinard Art Institute in Los Angeles, sold his first cartoons at age 15, and went to work as animator/production artist for Warner Bros in 1954. From 1957, he was the assistant of Hank Ketcham, ghosting on 'Dennis the Menace' Sunday pages.
He gave up 'Dennis' to start his own 'Ponytail' daily for King Features Syndicate in 1960. A Sunday page was added in 1962. Holley continued his strip until 1989, and also drew stories with his character for comic books by Dell (1960s) and Charlton (1970s). Since 2010, old episodes of the comic (both dailies and Sundays) also run in Dutch girls' magazine Tina, translated and adapted by Thom Roep. During the 1960s and 1970s, Holley also did art on comic books with Warner Bros characters for Western Publishing ('Bugs Bunny', 'Porky Pig'), as well as 'Tom, Dick and Harriet' (1976-78).
