In pictures: One Day in Latvia

In 1987 photographers from across the Soviet Union and, very unusually, some non-Soviet countries too, travelled all over the Latvian Soviet Socialist Republic taking pictures.

They had planned to publish a book of the photos, but couldn’t raise enough money and the project was forgotten amid the turmoil of the collapse of the Soviet Union and Latvian independence.

But 20 years on, 150 photographers have revisited many of the areas pictured in the original project.
