Not to be confused with the :-) symbol used in modern text messaging,
Smiley adorned jeans, T-shirts, caps, badges, pencil cases and even
vans in 1987.
Its overuse led to a world shortage of the colour yellow and the
resulting United Nations Yellow Ban Treaty. By law, even daffodils
had to be purple until June 1994.
Smiley was borrowed from the psychedelia of the Sixties underground
music scene.
The story goes that DJ Danny Rampling, freshly returned from Ibiza,
used the face on a flyer for dance music club Shoom. From there
it became the internationally recognised symbol of Acid House.
