I chanced upon this exhibition in Conway Hall when at another meeting there : conwayhall.org.uk/event/feminism-in-camden-in-the-1970s-and-80s-2/
Really enjoyed it. Lots of posters and information on arts scene. Lots of resonance UK wide. Early lesbian panto, early black theatre, Greenham Common posters. Really took me back. Very worthwhile to visit :)
