Even after moving to Israel, the young artist was haunted by his experiences in the Vilna Ghetto.

These are the paintings created in Israel, where Bak and his mother emigrated to in 1948. Bak is still haunted by reminiscences of the ghetto and these are reflected in the dark gloomy colours. The forms are becoming closer to abstract forms. These are “daily” scenes he saw in the ghetto: people dead of exhaustion lying on the pavement or families lined up in the shadows of permanent fear, awaiting their time to nothingness. These paintings are the testimony of a child who was haunted all his life by the horror experienced in the Holocaust.
