NVI Machins 1989-2017
Introduction
The British Non-Denominated Definitive Series
A Study in Production Materials, Printers and Process
and the Resulting Varieties
Purpose: This is an exhibit of stamps which documents the introduction, variety and expansion of non-denominated or No-Value-Indicated (NVI) printings in the United Kingdom.
Treatment: Royal Mail introduced NVIs in 1989. Starting as a simple set of 1st & 2nd class Machin postage stamps, this effort has grown to encompass additional letter rates and National & Country stamp designs.
This period of stamp production encompasses many of the significant technological changes to UK definitives that continue to require a stamp to be a complex, multi-layered, mechanisation-interactive device. Forces compelling these qualities of modern UK definitives include Post Office service and cost considerations, regulatory, nationalism and environmental factors, security, ease of use and rate escalation - all across multiple printers. The chapters of the exhibit will explain at a specialist level the resulting evolution of the NVI definitives.
Scope: The exhibit includes Test, Proof, Trial and production printings of National and Country releases.
