I am very interested in this suject and have read many books on the sapnish Civil war, especially on the International Brigaders who came and fought for the republic agaist Franco's rebels.I have also done extensive reseasrch on the posters and propoganda used on both sides to make this intranational conflict an international conflict. I recommmend this book "Palette and the Flame" (by John Tisa)for those who are interested in the posters used by the republicans in this war. I highy recommmend this book "Shouts from the Wall" because it is very comprehensive and informative. The photographs are amasing and moving. Viewing this book makes you aware of the time and the situation of these brave soldiers who fought to end fascism.
