Along with the great cut and paste DIY sleeves from the period, the Xerox posters and flyers for punk shows very much tell the story of the times.
In recognition of this Paul Cooper is co-curating an exhibition of punk fliers 1976-2000 at Rough Trade East in August and is looking for anyone who may have UK fliers from that period that they would like to donate (photocopies are fine).
Anyone with private collections can or bands who may have kept an archive get in touch with firstname.lastname@example.org. Any donations will become part of the permanent collection that tour the world. Here is the website where the European fliers are archived.
