casings to house them. Before the last two humanoid Daleks die, exhausted by their labours and the effects of radiation, it appoints itself as Emperor and has a special casing constructed to reflect its new rank, made from "...Flidor gold, Quartz and Arkellis flower sap...". The Golden Emperor is usually depicted as being slightly shorter than a standard Dalek with a disproportionately large spherical head section. The title page of The Dalek Book lists three contributing illustrators; Richard Jennings, John Woods and A.B. Cornwell. As none of the stories are individually credited it is uncertain which artist or artists first developed the Golden Emperor design. Two illustrators provided interpretations of the Golden Emperor for the TV21 comic strip; Jennings again, and Ron Turner who superseded him in later instalments. "The Dalek Book" Daleks The Dalek Book (1964) is notable, although not unique, in portraying a Dalek variant which has a "speaker grille" set centrally on the chest and, occasionally, a stylised numeral on the dome. Neither of these items has ever been incorporated in a Dalek variant shown on-screen. During rehearsals for the first Doctor Who serial in which they appeared a numbered piece of card was taped to the dome of each Dalek prop to assist the director in distinguishing them, with a tape roll being wedged behind the top front collar for safekeeping. These objects subsequently appeared in reference photographs of the Daleks provided by the BBC to merchandise producers, with the illustrators of The Dalek Book interpreting them as speaker grilles and insignia. Shortly after the publication of this volume other merchandise and packaging appeared featuring Daleks with the speaker grille design element. These included Dalek board games, bagatelle, "Cutta-Mastic" polystyrene sculpting sets, marble mazes and a ray gun torch. Dalek Emperor A Dalek Emperor, described as being similar that seen in The Evil of the Daleks, appears in the Telos novella The Dalek Factor (2004) by Simon Clark. It is referred to as "an Emperor", implying there is more than one during the period in which the story is set. Dalek Prime A Dalek Prime is referred to in several of the novels based on Doctor Who serials (The Chase, The Daleks' Master Plan, The Power of the Daleks, The Evil of the Daleks). It is also mentioned in John Peel's Eighth Doctor novels, War of the Daleks (1997) and Legacy of the Daleks (1998). Although
