where can you buy this!?

This one was a giveaway by a retailer for fans of the Dutch Soccer team. PPL were expected to use it when the team scored. Never became a huge hit, as you can't see anything with that flap up. Stupid design error…

Day One:
“Check it. Regular shirt with a sweet ass lion on it right? But then bam! ROOOOOOAAAARRRR!!! Isn't that ultimate awesomeness!? One Month Later:
Fuck… here comes Ken in that stupid lion shirt… no don't look at him! He-
“ROOOOOOAAARRRRRR”
Fuck…

Where can one obtain such an item?
