In 1936, after the king's death, Sir Percy Vincent, the then–Lord Mayor of London, formed a committee to determine a memorial that was not solely based on the idea of a statue.
In March 1936, the committee decided that there should be a statue in London and a philanthropic scheme of specific character that would benefit the whole country and be associated with King George V's name.
As a result, in the November of that year, the King George's Fields Foundation was constituted by Trust Deed to give effect to the scheme.
The urbanisation of the twentieth century in Great Britain was bringing home to many public-spirited people the fact that lack of open spaces must restrict the rising generation physically.
Each field would have a distinctive uniform tablet as an appropriate visible commemoration of George V. This was considered to be as the King would have wished, particularly in the service rendered to youth through providing for them an environment and opportunity for open air exercise, for the benefit of individual well-being and the general welfare of the nation.
Playing fields were to be acquired, planned, equipped, maintained and safeguarded for recreational purposes in towns and villages throughout Great Britain and Northern Ireland.
To determine the best ways and means in which to remember George V, and to put in motion the necessary machinery to raise the required funds, a national appeal was set up.
The Foundation found at the outset that half a million pounds was not enough to meet the costs of acquiring fields and maintaining them for all the places in the country where they were needed.
The National Memorial Fund Committee had concluded that the maximum results might best be achieved by 'distributing the funds by way of grants-in-aid towards the capital costs of as many fields as possible', the balance of the capital required for each scheme to be raised by the local authorities or local bodies of Trustees managing and accepting responsibility for their maintenance as King George's Fields.
To avoid duplication of effort and minimise administrative costs, the Foundation consulted the National Playing Fields Association (NPFA) and its affiliated county organisations.
Among the factors taken into account by the Grants Committee were the population, number and size of existing playing fields, and local economic conditions.
Some very large schemes emerged; the largest King George's Field in Enfield, London, covers approximately 128 acres (0.5 km2), providing many pitches for a variety of games.
The Foundation, very much aware of the concept of a National Memorial, required security of tenure over the land and its dedication for permanent preservation as a 'King George's Field'.
This means that any plans by a local trustee require the consent of the NPFA, which has the duty of preserving the King George's Fields.
The NPFA was also given powers to use the remainder of the funds available for repairs or renewal of items of a capital nature including the replacement of heraldic panels.
On 3 November 1936, the King George's Fields Foundation (KGFF) was constituted as a charitable trust to give effect to the scheme.
The objects of the trust were "to promote and to assist in the establishment of playing fields for the use and enjoyment of the people throughout the United Kingdom of Great Britain and Northern Ireland".
In cases where a field was unfenced no actual gates would be necessary but piers bearing the heraldic panels might be placed as pylons to mark the most important point of entry.
In the case of England, Wales and Northern Ireland, the panel on the left is the Lion, holding a Royal Shield, with the words 'George V' underneath, and below them 'A.D.
