It is a normal shirt and not a signed shirt. Dang that would have been epic if it is the signed shirt but its definitely isnt.
The buy in for the 1btc tourney was 0.001 btc with 500 shirts to be given away also less than 200 participants, I cant remember the exact number but everyone should be able to get a shirt if they requested it . The signed shirt cost 0.05 btc, would have been great bargain to get 0.05 btc goods for 0.001 btc
Just my speculation but probably the delay for the shirts from What Bitcoin Did Tourney was because it wasnt handled by sportsbet but it was handled by the whatbitcoindid podcast. We were asked to input our shipping details in the whatbitcoindid website instead of sportsbet site so yeah ( just my speculation though )
