Here's the picture of the 1940 cleaning crew which Henry Jablonski refers to in the interview I conducted with him. He says that he is in this picture with his father - he started his career at Dubrow's as a boy and worked as a dishwasher. His father (Henry Jablonski Sr) was a counterman.
Mr. Jablonski is the the young-looking boy who is fourth on the right. His father is not in this picture. The hand-written caption on the picture also names Mike Nagreski (spelling uncertain) and Pete Kolody and "German chef."
