I had no idea what the panel or book was about, but I stayed, and it ended up being quite interesting!
The book is a collaboration between 54 comic artists, covering 54 days in the life of the title character Nel. Each artist did a day each (which was one day per year, so the book spanned 54 years, with a single day each year being told), and they had quite free reign to come up with their part of the story as well as doing the imagery for it. All the profits from the book are also going to charity.
At the panel there was one of the editors, Rob Davis, as well as four of the contributers. They spoke about how they each went about thinking of their day/year, and what it was like collaborating.
None of the artists knew what others had written before or after their day/year in the story, so I'm sure it was probably hard to make sure it all came together for the final product. Each artist worked independently and just liased with one of the editors, who gave minimal notes on the work, you know, like dont kill off the main character etc.
There are a couple of names in there that I recognised such as Luke Pearson and JAKe, but other than that I didn't know any of them, but having a flick through the book at the stall later, they all looked fantastic.
Overall I think it was interesting to hear about a successful collaboration project and how they went about it. Definitely seems like something that could be applied to just illustration rather than comics, too. Maybe something to think about for next year...hmmm...
