1970 Soviet stamp honouring Harry Pollitt and the SS Jolly George incident.
On May 10, 1920 dock workers in London, led by militant labour leader Harry Pollitt, refused to load munitions that were meant for counter-revolutionary forces in Russia onto the SS Jolly George. For 5 days the workers held out until the shipment was cancelled.
Pollitt went on to become General Secretary of the Communist Party of Great Britain which is celebrating its centennial this year.
This stamp was printed in 1970 on the 50th anniversary of the dock worker action.
Pollitt died in 1960.
