That stands for London Film and Comic Con, which I attended one and a half week ago. 

It was a pretty cool experience, since I've never been to one before, and there's an even bigger one apparently (Anna Quinn told me so) at the end of May, with more of everything, including cosplayers, so I guess I'll have to go for the last week of May next year instead of first week. 

 It was hard to get any decent shots of cosplayers, since there was crap backgrounds and other people everywhere, but here are a few shots anyways.
