The driving force behind the YZ range was Bernard Howell. He is credited with having initiated and developed the YZ concept. A talented artist, draughtsman and prolific cartoonist, Bernard's cartoons often depicted birds. His YZ characters are clever caricatures, designed by an artist who had the intuitive knack of emphasising individual characteristics in humorous form.
This page brings together all of the company's available depictions of YZ design.
