In the United States, the first time a combination of yellow and black was used for a smiling face was in late 1962. During the 1960s and early 70s, a number of designers created smiling faces, which were categorized as "happy faces." The WMCA happy face became synonymous with 1960s culture in New York City. The New York-based radio station used the happy face as part of a competition for listeners. When the station called listeners, any listener who answered their phone "WMCA Good Guys!" was rewarded with a "WMCA good guys" sweatshirt that incorporated the yellow and black happy face into its design. Throughout the 1960s, thousands of these sweatshirts were given away. The features of the WMCA smiley was a yellow face, with black dots as eyes and had a slightly crooked smile. The outline of the face was also not smooth to give it more of a hand drawn look. Originally, the yellow and black sweatshirt (sometimes referred to as gold), had WMCA Good Guys written on the front with no smiley face.
