International Labour Research and Information Group (ILRIG), Mayday, 1987. Silkscreen poster produced and printed at CAP, Cape Town. Artist: Probably Clive Helfet. Campaigns commemorating days regarded as symbolic were a powerful mobilising tool in the anti-apartheid struggle in the 1980s. The campaign to have May Day officially recognised sought to link the struggle of South African workers with international labour struggles. Collection: CHR/UWC-Robben Island Museum Mayibuye Archives
