A small gallery in the suburbs of Tokyo is hoping to share with the rest of the world a series of paintings by a couple who witnessed the aftermath of the atomic bombing in Hiroshima 75 years ago.

The 53-year-old museum that displays works by the late Iri and Toshi Maruki, who were nominated for the Nobel Peace Prize in 1995, started an online fundraiser in June to create a short video introducing the paintings, known as the Hiroshima Panels.

Combining Western and traditional Japanese painting techniques, the husband-and-wife artists spent more than 30 years creating a set of 15 large paintings depicting the horrors of the U.S. atomic bombings of the cities of Hiroshima and Nagasaki at the end of World War II.
