Kent emigrated to England in 1959, working in advertising before his Grocer Heath strip was published in Private Eye in 1969. Varoomshka appeared in The Guardian from 1969 to 1979, Kent also contributing work to The Sun, The Daily Mail, The Sunday Times and, from 1998, The Times, where his La Bimba strip showed clear echoes of the earlier Varoomshka.
Kent's career trajectory involved a transition from advertising to comic strips. His work included the "Grocer Heath" strip in Private Eye, followed by "Varoomshka" appearing in The Guardian, and later contributions to other publications like The Sun, Daily Mail, Sunday Times, and finally The Times with his "La Bimba" strip.
