Over the past 30 years Onslows has sold only a handful of posters from the Spanish Civil War (1936-39), but this selection has an interesting provenance dating back to 1937.

Patrick Bogue of Onslows says: “The collection we are to sell originally held 12 posters. However, the family who have owned them since the conflict decided to present five examples to family members, in memory of their relative who had collected them while in Spain in the 1930s as he supported the Republican cause of the war.”

The “commitment of artists to the Republican and anti-Fascist cause made the Spanish Civil War posters vigorous,” adds Bogue. The two designs pictured here reflect that view.
