In 1893, New Zealand postage stamps were printed with advertisements on the back. That is, until the people rebelled.
"People weren't very happy about licking the backs with the adverts on the back," a Wanganui man said.
The man, who wanted to only be known as Laurie, thought those stamps were some of the most interesting.
"After six months the public rebelled and said 'no more, we don't want to lick these dirty stamps."
Laurie, a collector, was just one person browsing at the Wanganui Philatelic and Numismatic Societies - otherwise known as stamp and coin collectors - annual show on Sunday.
