Casual socks from COPA Football from the official FIFA Classics collection. The Argentina 1978 World Cup socks feature an all-over print featuring the official mascot of the '78 World Cup. The mascot's name is Gauchito. A boy wearing Argentina's uniform. His hat (with the text ARGENTINA '78), neckerchief and whip are typical of gauchos. The COPA casual socks are also completely in navy blue. The socks are produced in Italy and are made of 85% cotton, 12% nylon and 3% lycra.

The official mascots are a set of unique characters for each event. The tradition of the official FIFA World Cup mascots started in 1966 during the World Cup in England with a lion named World Cup Willie. Willie was one of the first mascots associated with major sports leagues. The mascots represent a characteristic of the host country, such as flora, fauna or costume. The characters are aimed at children and coincide with shows and merchandise.

The FIFA Classics World Cup collection from COPA Football consists of several t-shirts, casual socks and sock box sets which feature the official World Cup posters, emblems and mascots from various World Cup football.
