A study of the Imperium style key plate issues within the 16 colonies that employed this design. The formats of the key plates are determined and a detailed plating study of Key Plate 1 is provided, a rare example of such a study on a surface printing plate, whilst the ‘Spaven’ and ‘Missing Frame’ flaws are examined in depth. Philately has long misunderstood the format of Key Plate 2 and its true size and format is revealed. A study is made of the damage sustained to the marginal areas of the plates, particularly the marginal rules, which can assist in determining the date of printing of certain marginal examples. Individual colony sections list all printings for each colony and the use of ordinary or chalk-surfaced paper is recorded for all printings. The basis on which the plate number allocated to each printing has been deduced is given. Additional information has been derived from the De La Rue and Crown Agents records, together with that from philatelic literature, and any exceptional events noted.£18
