Are footballs really made of pig skin?
Football
In Europe, early footballs were made out of animal bladders, more specifically pig's bladders, which were inflated. Later leather coverings were introduced to allow the balls to keep their shape. However, in 1851, Richard Lindon and William Gilbert, both shoemakers from the town of Rugby (near the school), exhibited both round and oval-shaped balls at the Great Exhibition in London. Richard Lindon's wife is said to have died of lung disease caused by blowing up pig's bladders. Lindon also won medals for the invention of the "Rubber inflatable Bladder" and the "Brass Hand Pump".
Kit (association football)
Football kit has evolved significantly since the early days of the sport when players typically wore thick cotton shirts, knickerbockers and heavy rigid leather boots. In the twentieth century, boots became lighter and softer, shorts were worn at a shorter length, and advances in clothing manufacture and printing allowed shirts to be made in lighter synthetic fibres with increasingly colourful and complex designs. With the rise of advertising in the 20th century, sponsors' logos began to appear on shirts, and replica strips were made available for fans to purchase, generating significant amounts of revenue for clubs.
