Come for the free comics, but stay to make your own! It's for ages 6-12 and I promise that it will be fun!
Also, they should have copies of the Cor! Buster Humour special on sale. I wrote some comics for that, so you should buy that too!
More details here: https://www.goshlondon.com/events/fdbdkids and I very much look forward to seeing you there
