New Zealand: 1857 or 1862 1d dull orange, "Dwarf", used.
Engraver: William Humphreys
The early stamps of New Zealand were printed on the same type of printing presses as those used for the Penny Black of Great Britain. Initially they were printed in London, but later in 1855, the printing plates and a press were sent to New Zealand.
This locally printed 1d. stamp shows a remarkable variety, which is thought to have occured because the plate was underinked, or in some other way poorly printed. It is believed that when the printer noticed this, he tried to correct the mistake by printing another impression on top of the first.
Because the impressions were not accurately ligned up, the stamp has a short appearance, and so is known to philatelists as known as the “Dwarf” error. Only two examples are recorded.
