The son of a US military veteran is trying to track down the identities of a number of US soldiers featured in portraits sketched by his father during World War II.

Ira Dube found the sketches in an attic and has now enlisted the help of a New York museum to find the families of the servicemen.

Dube’s father sketched the portraits in 1943 during downtime in Hawaii. A year later his Infantry Division was decimated in the bloody Battle of Saipan.
