"Workers of the world unite" - the masses gather to see the unveiling of the Marx memorial in Highgate.

"Workers of the world unite" - a crowd gathers to hear speeches from Communist luminaries, including Arthur Horner and Harry Pollitt, to mark the unveiling of the Marx memorial in Highgate Cemetery. This was filmed by renowned cinematographers Wolfgang Suschitsky (Get Carter) and Bryan Probyn (Badlands) in uncharacteristically low-key style.

Produced by Plato Films but never released in Great Britain; it was financed by the Socialist countries through the services of Andrew Rothstein, who appears alongside Harry Pollitt, Arthur Horner and J.D. Bernal to speak at the occasion of the unveiling of the memorial in Highgate Cemetery.
