This large watercolour is a design for a mural. It reflects the political mood in Britain before the Second World War. Opinions were polarised between support for the left and the right, and Gilbert Spencer sought a landscape subject that would show his commitment.
The Tolpuddle Martyrs of 1834 were a popular example of trade union history. They were farm labourers from Tolpuddle in Dorset who were prosecuted for combining together to insist on an increase in their pay. Gilbert Spencer shows his characteristic farming subject in the light of historic social unrest. The mural was never painted.
