You know Mundial mag as the spectacular-looking, beautifully-written, thinking fan's take on the game we all love.
Their latest venture is aimed at a different audience though.
The Big Book of Football is for kids - a gloriously-illustrated introduction to everything that's great about the world's greatest sport... but it will definitely appeal to the big kids, too.
We caught up with Mundial's James Bird to find out more.
CK: Tell us, when did the idea for the book start?
JAMES: Officially, we were approached by Wide Eyed Editions, part of the Quarto publishing group, just over a year ago and asked if we’d like to write a kids book. But, really, I think everyone has an idea for a children’s book and probably wants to write one. So the opportunity for us, as people that work at a football magazine, to write one was never going to be turned down.
And, as you get older you remember the things you read as a kid with more fondness and realise that they probably had an impact on who you are as a person now. So, hopefully, this can serve as an introduction and celebration to all of the things that make football so brilliant for another generation.
