Magpie moth

It shows in detail the plate flaws arsing from the printing by Harrison & Sons of London of the 2 1/2 c Magpie Moth stamp which was one of the stamps of the 1970 Pictorial set issued by the New Zealand Post Office. Included are 200 drawings depicting the flaws on each of the plates 1A and 1B. Some of the minor flaws shown have been found to be only temporary in the sheets produced from these printings. This stamp was later (1971-73) surcharged 4c due to a change in postal rates and a lack of 4c Puriri Moth stamps in New Zealand. It was primarily by examining these surcharged stamps that Watanabe was able to document in this book the Magpie Moth plate flaws.
