From 1891 some stamps affixed to official government mail were overprinted by rubber stamps at time of posting with the letters 'O.P.S.O' - 'On Public Service Only'. More commonly, various forms of special printed or rubber-stamp franks were used.
In August 1906, Government decided that "as from 1 January next, the existing system of franking letters, packets and telegrams sent on public service, is to be abolished, and that in lieu thereof such correspondence is to be paid for by means of official stamps". Several of the current pictorial stamps of the day, together with the Penny Universal stamp, were overprinted with the word 'OFFICIAL' for this purpose.
The 1/2d stamp was designed by H W Young, the 1d by Guido Bach, the 2d, 3d and 1s by W R Bock, the 6d by E Howard, and the 2s and 5s by E T Luke.
