Lionel Messi's Barcelona Napkin Contract
Lionel Messi is among the greatest footballers ever, winning a record 8 Ballon d'Ors, a World Cup, and a slew of club championships. That legacy was far from assured when Barcelona signed the then-13-year-old in 2000. They did so, in the absence of proper paper, on this napkin. Signed by Barcelona sporting director Carles Rexach as well as agents Josep Minguella and Horacio Gaggioli, it's one of the most consequential documents in soccer history.
