The year 2021 is significant for the Wanganui Philatelic Society.
The club was formed in 1896, went into recess in the early 1900s and restarted in 1921. As stamp collectors, when a significant date comes along, club members will endeavour to commemorate it with the issue of a special stamp.
Such was the case in 1990, when a planning committee from the society was set up to design and produce a special miniature sheet to mark New Zealand's sesquicentenary (150-year anniversary since 1840).
An application was made to the Wanganui District Council Sesquicentenary Committee for it to be an official anniversary commemoration, which was granted, along with some funding to promote the project.
The design of the miniature sheet was planned by the committee to include local and Wanganui district scenes. As well, the sheet would have a Wanganui logo design showing the river, the Wanganui City Coat of Arms and the official 1990 Sesquicentenary logo. Four Wanganui scenes were chosen and photographed specially for the sheet. They were the Sarjeant Gallery, Moutoa Gardens, Koriniti Meeting House and a Whanganui River scene.
