World Cup Matchballs is a very cool new site created by Italian media company 150 up. It showcases all the match-balls of World Cups gone by, from the 1930s up to present day in Brazil 2014.
The site is a colourful responsive one pager showcasing the official World Cup footballs used every four years. Great job on the illustrations and additional bonus info on each each year.
