What's the Era of the "Pure Wool" Symbol?

[eniksleestack]

Anyone know when the wavy-triangular pure wool symbol started being used on clothing tags? There must be an easy way to date clothing based on its use on tags.

Additionally, does anyone know of a good vintage clothing tag resource/ ID website?

Thanks in advance!

In 1937, a non-profit organisation was formed internationally with the establishment of the International Wool Publicity and Research Secretariat, later known as the International Wool Secretariat (IWS). The IWS comprised major wool producing nations and its original members were Australia, New Zealand and South Africa.(1) Its purpose was to build and maintain the long term demand for wool. IWS undertook the international promotion of the use of wool, both commercially and by research into woollen fabrics.(2)

Since that time the IWS has been responsible for the promotion and marketing of wool and its products as well as research and development in wool processing and refinement. In 1964 the IWS established the 'Woolmark Program' that introduced the 'Woolmark' brand, now widely recognised internationally. The 'Woolmark Blend' symbol was introduced in 1971 while the 'Wool Blend' symbol came out in mid 1999. However, by 1972, the IWS was considered to be the major wool promotion organisation in the world.
