Looks really good.
There is good stuff on the origins of the International Brigades in East London Communist Joe Jacobs' book Out of the Ghetto. He describes how three tailors from Stepney first went to fight in Spain, much to the disapproval of the Communist Party. Later the CP got behind the International Brigades (costing them many of their leading lights, like the polymath, Christopher Caudwell). -- James Heartfield
