Details: This poster shows a variety of smiley faces against a purple background. At the bottom it says 'Smiley World'.
A smiley, or happy face, is a stylized representation of a smiling human face, commonly represented as a yellow (many other colors are also used) circle (or sphere) with two black dots representing eyes and a black half circle representing the mouth. 'Smiley' is also sometimes used as a generic term for any emoticon. The variant spelling 'smilie' is not as common, but the plural form 'smilies' (the plural of 'smily', not 'smiley') is commonly used.
