Last year, a special spoof stamp was created for April 1 by a
Scarborough (Yorkshire, UK) collector.

Christopher Phillips, secretary of the Scarborough Philatelic Society,
designed the one-off “junk mail” stamp to remind people to place
unwanted mail in the wastepaper basket and not be “fooled” into buying
things they don’t want.

The stamps were be given out free to members of the Scarborough group
and some were be sold to collectors on auction website Ebay.

Mr Phillips has been producing the April 1 stamps since 2007, when he
created a topsy-turvy version of a first class stamp with the
lettering “Airmail Post to Southern Hemisphere”.

He said: “I thought it would be rather fun and our members thought the
stamps were great.
“People from as far away as Australia bought the stamps and they
proved quite popular.”

Mr Phillips has used the stamps when sending letters to people, but he
added that you must always use a normal stamp too and put the fun
stamp elsewhere on the envelope.

The SPS also celebrated its 70th anniversary last year and more one-
off stamps and events are in the pipeline.

The group is always looking for new members and meets at 7pm for
7.30pm on the first Tuesday of each month – but if the Monday is a
Bank Holiday, it is the second Tuesday of the month.
