One of two button cards presented to the museum by Acas, The Advisory, Conciliation and Arbitration Service, a Crown non-departmental public body of the Government of the United Kingdom. In 1976 Acas was asked by the then Secretary of State for Employment, Mr Albert Booth, to commence an inquiry into the regulation of the pay and terms and condition of the workers in the button manufacturing industry and the operation of their Wages Council. Whilst collecting evidence for the inquiry, Acas was given two sample sheets of buttons by the British Button Council. The letter of thanks sent by Acas, dated 8.2.1977 was deposited in the National Archives. The two button cards, of which this is one, contain examples of the materials most commonly used in button manufacture. The materials include aluminium, brass, steel, shell, leather, glass, horn, rubber, pearl, wood, melamine formaldehyde, polypropylene, polystyrene, cellulose acetate, urea formaldehyde, polyamide, polyester, and casein. The cards are undated but are thought to be from the 1970s.
