The figures depicted in drawings UTW 39, UTW 40 & UTW 40 were drawn in 1997 or '98.

They were drawn from a Warsaw ghetto photo. Each of the 3 people: a girl, perhaps a teenager, a boy who might have been adolescent age, and a bearded man, were photographed on a sidewalk standing within several feet of each other.

I drew the wings on the boy depicted in UTW 39 at the ornithology lab, Burke Museum, Univ. of Washington, Seattle, in 2018. I plan to draw wings on the victims portrayed in UTW 40 and 41 in 2019 or 2020.
