A few days ago (April 26) it was 70 years since Guernica (Gernika) was bombed and 1654 inhabitants out of a population of 7000 were killed.
Tomorrow (May 1) it was 70 years since Picasso decided to dedicate a painting he was already working on to Guernica.
It was exhibited already in July 1937 in the Spanish Pavillon (financed by the Spanish republican government) at the World's Fair in Paris. It then travelled to Scandinavia, London... before coming back to Paris. After Franco's victory, the painting left for the Museum of Modern Art (MOMA) in New York, where it with some interuptions remained until 1981, when it was ceded to a democratic Spain. You can now see it at the Reina Sofia museum in Madrid. There is a discussion ongoing where the Basque nationalists would like to see the painting at Guernica or in the Guggenheim Bilbao museum.
