Never been to one of these before. It's a real education. So much visual information everywhere you could easily spend the whole day and not see it all.
Some people indulge in what's known as Cosplay, though I think the above might more properly be called Fancy Dress.
Definitely one of the best costumes there.
Got talking to these guys for a while.
Gradually it dawned on me that they're actually kind of famous.
