In 1957 New Zealand began the tradition of issuing stamps to celebrate Anniversaries. There had been some before this but only for cities and provinces. This changed in 1957 when NZ Post began issuing stamps celebrating the anniversaries of important events and organisations.
The two issue below were actually released at separate times during the year but we have grouped them together for this post. First we have the 1957 Lamb Export 75th Anniversary and then we feature the 1957 Plunket Society 50th Anniversary.
