1922~24 KGV 4d BLUE imprints, HARRISON printing
THE 4d blue imprints are the rarest of all the KGV imprints. For one to complete the set will require 6 imprints. When Harrison took over from Cooke he removed the Cooke monograms and installed a single line imprint “Harrison Australian stamp printer” and later a 2 line imprint “Harrison Australian note and stamp printer”.
There are the two variations on the Cooke plates 1 and 2 and the later two line imprint on the Harrison plates 3 and 4. To complete the set the market value is app $80,000.00. Above all it is not an easy feat considering there are around 12~15 blocks.
NB. We don’t know of any collector who has managed to achieve this feat. Even Arthur Grey collection had five only.
