From the Museum of Tolerance web site:
"This picture was taken by some Kraut, who handed it right back to us to be developed. Then we made ourselves copies on the sly. I had no idea that they would still be of any use to anyone. "In Krosno the Jews were rounded up in the market square, and then the transports left for the death camp at Belzec. The Jews were jammed into the back of open trucks and driven around the whole city for everyone to see. That was the last time they were seen."
