Who designed the ship logo for the British children's TV show "Blue Peter"?

Norman Antony Hart (15 October 1925 – 18 January 2009), known professionally as Tony Hart, was an English artist best known for his work in educating children in art through his role as a children's television presenter.

Hart initially worked as an officer in a Gurkha regiment until the start of Indian independence. After this he became involved in children's television from the 1950s, working on the BBC's Blue Peter for a few years before fronting a series of children's art programmes, including "Vision On", "Take Hart" and "Hartbeat".

Hart's contributions to children's television include the design of the ship logo used by "Blue Peter" and the show's badges, and the animated character of Morph, who appeared beside him on his programmes following his introduction in the 1970s.
