I found Breaking Free at random in a Brighton bookstore decades ago and it remains a cherished treasure. Glad to see someone else out there enjoyed it!
I picked it up from an anarchist stand at a comic convention in the late 1980s, where else! I don’t know where it is right now, and I’m not sure it’s a cherished treasure, more an amusing memento of my youth! Although I will be most annoyed if I can’t find it!
