Joan Porter was part of Frank Hampson's studio working on "Dan Dare" in the British comic Eagle, primarily as a colourist, although she also did research, photography and secretarial work. She was part of Hampson's studio from 1950 until it was disbanded in 1959 when Odhams Press took over the Eagle. Later, she assisted Hampson on "The Road of Courage", a retelling of the life of Christ. Hampson wrote to her at one point, saying "Wherever I am and whatever I am working on I shall want you for the colour."
