Carter eventually returned to London where he became a freelancer. By 1961 Carter was able to use the skills he acquired to cut his own version of the semi-bold typeface Dante. An early example of his work is the masthead logo he designed for the British magazine Private Eye in May 1962, still in use. Previously the lettering had been different for the masthead of each issue; it was based on a font ('a bit of nameless juvenilia') which was never ultimately published. He also did early work for Heathrow Airport.
