Recognizable socks in dark gray from the COPA Football brand. On these COPA socks, Rensenbrink can be seen in the Dutch national team uniform in the World Cup final against Argentina in 1978. The final was won by the Argentines after extra time. These casual COPA socks show Rensenbrink shooting the ball past goalkeeper Fillol, but it eventually lands on the post: the score remained 1-1. The casual COPA socks are produced in Italy and are made of 85% cotton, 12% nylon and 3% lycra.
