Diptych sculpture - Unsigned plywood, possibly an allegory of deportation?

Superb wooden diptych featuring a window and an inverted triangle, which together form a Star of David. The blue stripes suggest a prisoner's pajamas, and the background is covered with excerpts from Hebrew newspapers. See the photos: do they suggest a wagon window? Each panel measures 25 x 46.5 x 4 cm. Unsigned Ref. 1-4
