Multiple Strikes of the Maltese Cross
IntroductionAn "Obliterating Stamp", in a shape now referred to as a Maltese Cross, was issued to all Postmasters shortly before stamps were made available to the public. Along with the Maltese Cross obliterators, Postmasters were also sent instructions for the obliteration of postage stamps, as well as details for the red stamping composition to be used.
The Maltese Cross was the world's first obliterator and the lessons learnt from its use would go on to influence the design and use of future obliterating handstamps, throughout large parts of the world, for years to come.
Although the intention was that the Maltese Cross obliterator would be used only once for each stamp, multiple strikes of the Maltese Cross are sometimes referred to incorrectly as contrary to regulations, which only stated that each stamp must be separately obliterated:
"You will carefully Stamp with the Cancelling Stamp that has been forwarded to you, the stamped Covers and envelopes, as well as the adhesive stamps, the two former must be struck on the figure of Britannia, and in the case of more than one adhesive Stamp being attached to a Letter, each Stamp must be separately obliterated." - Edward Lees, Secretary of the Scottish General Post Office, April 1840
This display considers why, contrary to intentions, the Maltese Cross was used multiple times on the same cover thus increasing the workload of the clerks and introducing inefficiencies during its period of use from 1840 to 1844.
