Introducing Logic: A Graphic Guide

I don’t like“Introducing Logic: A Graphic Guide” as much as “Introducing Mathematics: A Graphic Guide” because, First of all, it doesn’t have as many pictures. Secondly, it is quite boring. Thirdly, it is quite tricky and hard. I hope that who ever reads this book already has a decent understanding of basic formal logic, as it is hard to find this type of person. I recommend this book for 15+
