I used to work in a store called Soccer Scene/Rugby Scene on Carnaby St in London. Around the time of the 2003 Rugby World Cup I managed to convince about 20 people to purchase the latest All Blacks RWC Limited Edition shirt and the reason it was Limited Edition was that it was signed by the entire All Blacks squad... IN BLACK MARKER!
This gives you an idea of the caliber of people who support the All Blacks!
