Two examples of this particular watermarked paper exist. One was found in the late 1990s in Hong Kong. A letter, written on azure laid paper sent from the Chief of Police to the Governor of Hong Kong was unearthed by a local sales representative of ArjoWiggins. The second example was a letter written in 1848, sent from Brooklyn, New York, USA to an address in Plymouth in which the writer was notifying his wife of his impending return to England.
British manufactured papers at this time often displayed combinations of the mill number, company name, mill name and initials or monogram of the owner or master papermaker. These were initially encouraged by an Act of Parliament and by including a watermark, to identify the paper and record its date of manufacture, the paper mill was able to reclaim excise duty.
