Some of the signatures are close but most are off and this does not look right to me. You have to ask yourself how likely is it that so many people got signed official shirts during the past 4 weeks? When I was at the 2006 World Cup it was almost impossible to get near team hotels etc so cannot believe much has changed
It is extremely difficult to find a team signed jersey/soccer ball. When they are genuine, they are very rare and expensive ($400+ depending on the team).
Dan Gregory is spot on- these forgeries pop up all of the time with every World Cup; it is extremely difficult to get even a handful of signatures on a jersey- let alone a whole national team!
